 Thank you. Thanks for attending my talk. I hope you had a great lunch and you are not too tired and You can have a nap, but just be quiet. Don't snore. I would love to have a nap, personally. So yeah, as Antoine said, I'm going to talk about PKG base, which is a big project in FreeBSD to use PKG to to distribute and update the base system. So first of all who I am. So my name is Emmanuel Vado. I'm Manuat FreeBSD.org. I'm a FreeBSD user since 2004. Source committers since 2016. In source, I mostly deal with arm and arm64 related stuff. I'm a FreeBSD port committer since 2018 and they are also deal with arm and arm64 related stuff, most most of all bootloaders. And I'm a freelance developer. So what is PKG base? It's using PKG for packaging and updating FreeBSD base, not really surprising from the name. PKG is a default package manager since 12.0, which means that every supported branch is using PKG. The old PKG tool have been deprecated. The goal is to split base into multiple packages. So that package manage and started a long time ago in 2015 by Baptiste Dawassin, Baptiste at FreeBSD. He first presented a talk at PSD Count 2015 and he started around January or February of this year. So it's been a long time. It was abandoned for a lot of time and I've picked up last March. So the goal are to provide binary upgrades for all the FreeBSD release, the FreeBSD stable branch, and the FreeBSD curable branch. It allows fine-grained installation. So if you want to have a system without send mail, without NFS, without toolchain because your appliance or your use case don't need it, it's better. So you can do that really easily. It allows PKG to deal with configuration file. PKG have a freeway merging mechanism where it's more or less you will never have any problem if you do some local modification on some files. So when you will update the base system and it will update a new default configuration file, it will do a freeway merge and most of the time you won't have any problem. And it allows developers to provide package for users to test. For example, if somebody said to me, okay, so I think that this driver is broken but I do not really know or want to compile a new kernel or some specific part of the OS, I can just send it to him one package and he will install it, test and provide feedback and then roll back to the official package. It also allows us to provide some, for example, some kernel package that enables some new flag, for example some new way of doing locking or whatever FreeBSD could provide a new kernel configuration, put some package and this will be easier for users to test those modifications and report problems. The goals are also that everything must live in the build system. So currently you build your package with the make packages targets. We don't want any external tool. So not using the port street, not using some shell scripts that live in a user branch or whatever, we want everything integrated in the build system. It needs also to be able to build and create packages as a user, no need for root accounts. And this is currently the case. It also needs to be able to create package for other architecture. It's really important for small embedded boards where if you want to build the base system or even the kernel, it could take ages. Sometimes you saw people on the FreeBSD Armani English that say, oh, yeah, I've just run a make build wall on my Raspberry Pi, which is running at maybe 400 megahertz on an SD card, a really slow SD card. And yeah, and two days later, I'm an age to do it or it broke. And you don't want to wait two days just to test an update or just to update your system. And so I wrote, I want people to create FreeBSD distros. What I mean by that is that I see a lot on the internet people creating Linux distros like based on Debian. For example, for our board, you have something called a pie hole, which is just a Debian based on a Raspian. So Debian distros for Raspberry Pi that are you to have a DNS hole and not have any ads on the internet on YouTube, etc. Having FreeBSD package will be way easier for people to create some FreeBSD distros that is done for a specific task. You could replace FreeBSD distros by Appliance too, but Appliance is like more professional way and distros is like, yeah, I just did that. I put that on YouTube and if you want to donate some money, so I continue, etc. These two Appliance is more professional. So how the package are generated? We first install a fake root during the make target called the wall stage and kernel stage. This is called automatically when you are doing the make package, package these targets. And so everything will be installed in your OBGD under the under directory called wall stage and kernel stage. And it uses two mechanisms. The first thing that it passes dash D no root, which will not call install with dash O option. So it will never set the correct ownership or set the correct rights. Instead, everything will be returned in a file called Metallog, which is just an M3 file. And so you will have the wall stage that are just a file just copied and associated with that you have a Metallog file where you find the correct right, the correct owner, etc. And TAR, more precisely Libre archive, which is used by TAR and by PKG, can read a Metallog file. And so when you will create the package, it will just read the correct right and correct owner from this file to be associated with the file. It also had some tags in the Metallog. So that's just M3 tags, which contains the name of the package and this will be used to choose a destination package for a specific file. By default, if someone, if some part of the build do not specify a package, everything will go to the free BSD dash utilities package. This is a package that I created last week or maybe two weeks ago. It used to be different one for the default package. It's it's done like that because it's just easier. I will talk about later on what's the plan to split the free BSD utility package. If you want more information on how this is done, you can look at the BSD.mk file in share the slash mk and you will see everything about the package creation. As I say, mk file can override the package by just putting package equal blah blah blah in the mk file and that's how you choose the target package. It uses UCL, so that's Universal Configuration Language. This is language used by PKG for the manifest file. It also used in base for different things. I think JAILs can use UCL file. What was the tool that you converted to C-Slog or new C-Slog? UCL is a bit used in free BSD. We would like more use of it and since package already used it, it makes sense to use UCL to define the package and all the UCL file that defines the package for PKG base are under the release slash packages directory and the playlist creation. To create a package, you have to provide a description of the package like who is the metna, what's the name, the version, etc. And you have to provide a list of file and this is automatically generated with the help of the metna log file. And what the make packages target does, it not only creates the packages, it also creates the repository. So at the end, you only have to R-sync or SCP, the directory and have it served either locally or by some HTTP and you can distribute package for everyone to use. So, pros and cons, it splits. First of all, we cannot please everyone if I think that some part of the base system should be in its own package, someone else will have some other arguments, not better, not worse, but another argument. So yeah, we cannot please anyone, everyone. So for now, since I'm the only one that's working on PKG base, well, I have my arguments and you have to deal with it. So unless you have a really better argument, we will go my way. Thank you. First of all, the current split is not final. In the past month, I've done a lot of commits that changes a lot of stuff and I'm still not done. I hope to Yeah, I hope to set up maybe in a month or two, but yeah, we'll see. So first of all, each kernel is in its own package based on the config file. What does that mean that you can have multiple kernel package? So for a release, think about distributing a generic package and a generic slash debug package so that would allow users to just install a new package to use the debug kernel, provide information to the user, etc. For current branch, the default is to build the debug kernel and have a dash, no debug. So the same thing, if you want to run current but don't have all the overhead of running debug kernel, well, you can choose and if you define your own your own kernel config, it will also be created and it will be in a package. We have, of course, FluBSD bootloader contains everything bootloader related, so that's all the file in slash boot except the kernel. So all the configuration file either Lua or Forth, etc. We have the SELIP package that contains the Serentime, so that's the runtime inical, libc, lib thread, etc. The reason is that they are in their own package is that so I'm not sure that I've understood everything correctly. There is a mail from Kibco-Sorten-Beliozov from April 29 on the PKG based mailing list. So you can have a look just to be sure that I've understood correctly. So all the external ABI are backrock compatible and will always work between, for example, an old binary is linked with an old libc, but you update your libc, it will work with a new libc. But all the internal between libc, lib thread, etc. are not stable and will never be stable. So you have to update them more or less at the same time. And if you put them in a really, really big package with a lot of other stuff, there is a lot of chance that libc will be updated first because alphabetically it's one of the first files and lib thread will be updated very, very long, very long time after, so you will most likely have a big breakage. And we'll have to boot from external media to recover your FreeBSD installation. We have the FreeBSD runtime package. This used to be the default to-go package. It was very big. It was, even at the time, it was not correctly named. So, and now it's even less correctly named. So I need to change the name. I still don't know how I will call it, but the goal is to have everything to be able to boot into a single user and repair on this installation. So this means is that if you install the FreeBSD kernel package, the bootloader, celebs, and runtime, you can boot onto a single user and have everything to repair UFS or ZFS disk. You have enough network tools to be able to configure the network and maybe grab some file, et cetera. So that's one of the goals. So maybe I will really need to FreeBSD core utils, but core utils is used in Linux. But yeah, I mean, the name makes sense to call it core utils, but I don't feel, so yeah, it will change. I still don't know what name I will choose. If you have any idea, please. What? Prepare? Oh, repair. Yeah, well, it's not only for repair. I mean, this is also tools that you need to have a full FreeBSD. Naming is hard. That's all. You have the FreeBSD-RC package which contains the RC sub-system. I've split those not so long ago for two reasons. There is some people working on OpenRC for FreeBSD, the IAC system guy. I don't know if we will ever see some port or whatever to be able to use that in FreeBSDvania, but at least know the RC file in their own package. And if you want to just experiment with another RC system, it will be easier. And also if you just take the FreeBSD runtime, the FreeBSD-C-LiP package, it's very handy to create a small MFS route that have everything to bootstrap to everything else. And most of the time when you do a small embedded MFS route, so that's a memory file system that is loaded by the kernel or integrated into the kernel, you will have a specific slash RTC RC file that just do what you want to do. So that's the reason it was splitted. And yeah, as I said, FreeBSD utilities, it's not the default package and it contains a lot of different things. Yeah, it's the to-go package, so there is still some stuff that I need to take out. Every package is also split with dash debug, dash development, dash profile package. That means that also debug file will end up into a dash debug, development file, so adders, etc., in their own package and same thing for the profile file. That's really useful for FreeBSD users because most of the time you don't need debug file, you don't need development file, you will just install your FreeBSD on your server, install some package and run it and if you have any problems, you can still install the dash debug file corresponding to the subsystem that you want to debug, do your debugging and remove the package. Same thing for development and profile. And this is done automatically based on the type of the file. On 64-bit ARG that have 32-bit support, so that's only MD64 for now. We also create some dash lib32 package. I don't know if anyone still use lib32 on MD64. I personally have no use for it. I'm pretty sure that there is a lot of use. I think that wine on MD64 at least used to use those, but I'm not sure anymore. Everything coming from Contrib, so some stuff that we pulled from another repository, are in their own package. The reason is that for security advisories or error attenuities, you are usually not, you could be not one in advance and since you need to roll out a package very very quick, it's easier to have this in their own package, so you will only have some part of the tree to roll distributes. FreeBASD tests contain all the test suites. Again, most of the time people don't care about tests. Users don't care about tests. Only developers should care about tests. And I'm not sure that a lot of developers do care about. I personally don't really, sorry. I'm bad for that. I know I'm bad. You can boo me. At least I'm honest. I know that other people will not say the same. So anyway, everything in the FreeBASD tests contain all the test suites. Maybe we should pull the QIA, some QIA binary, we have some QIA binary entry. Maybe we should just put everything in the test package. I don't know. And the other package are application or lib-specific. For example, I've created not so long ago FreeBASD does Bluetooth package. You don't need Bluetooth in a server, I hope. You don't need Bluetooth in a jail. Same thing for WPA, OSTAPD, etc. So I've created those packages. So if you don't want them, don't need them. Well, it's there for you if you want to install them. But I don't think that most of the people will use them. And yeah, I will continue to move things out of the utility package. Maybe I should move NFS out of it. Again, you don't need NFS in a jail, unless you have some really real jail setup. Same thing for Kerberos. I used to love Kerberos and use it a lot when I was at university. I don't think it's very, very used outside of the FreeBASD cluster right now. So maybe it makes sense to just put everything in a Kerberos package that will also possibly help if people want to install either MDAL or MIT Kerberos from Ports. You will not have conflict with the base Kerberos utilities. I don't know. So at the beginning of the package base, there was a lot of complain about the number of packages that we have. It used to be around 800 that was, if you count debug, development, profile, and lib32 package, apparently it matters to some people. For me, it only matters because if you have a really huge amount of package, the first time you install is very long. It's way longer than what we are currently doing, which is just extracting base.txt and kernel.txt. Instead of dealing with two TAR files, you're dealing with 800. So of course it's longer. I personally don't really care. Apart from these reasons, I don't care to have a huge number of package as long as the splitting is done in a logical way. At least one that could be explained. Right now, we have 300.92 package. If you don't count the debug, development, profile, it's only 118. And if you don't install lib32, it's only 80 package, which I think is good. It's not that long to install. As I said, I will continue to split up some stuff off the utility package, but I think we can have a target of around 100 package and it will still be okay performance-wise. So, yeah, that's what I'm planning to do. So, in Flubia's system, we have a with and without. In Assassin's Creed.conf, it's at control what will be built. And also, if we build with some library supports, with PKG base, you have two ways. Well, there is two things that will happen if you start to tweak. If, for example, you don't build without APM or without MD, those package will simply not be created. If you don't build, for example, without Capsicum, it will change the content of the package. For now, there is no resolution. Ports have a mechanism called Flavors. So, we can maybe add something like that that we have, for example, FreeBSD-utilities-noCapsicum. I don't really have a plan for now to work on that, but yeah, we need something. Another complaint about from user was, yeah, each time I'm rebuilding my system, I make the package, I need to reinstall and upgrade every package even if the content haven't changed. And this is true if you just do what I just said, so make packages and distribute the package. The thing is that there is a way to provide some good package just that it was never documented. I think that must slide as the only documentation, so I will try to put that on the FreeBSD Wiki, which could be useful for people. So, the first thing is to define with ReproducerBuild. ReproducerBuild will strip all the dates in compiled binaries, et cetera. So, that means if you use the same compiler to compile the same source at any point of time, you will have the same binaries, the same binaries produced. This is the default on release and current, and it's not the default on, sorry, release and stable, and it's not the default in FreeBSD current. You need to define source date epoch. That's the variable I, yeah, I think I spent whole afternoon searching for this variable, and when I say Baptiste, oh, I need to do that. Yeah, I didn't, I tell you about it. No, you didn't. So, yeah. This is used to tweak LibarCive output. It will just set the timestamp to every file to the timestamp that you set in this variable. You need to pass ReproducerBuild to make to have the repository add some pass in your system. You make packages, and then you can distribute. So, this is how you bootstrap your package. For example, for 13.0. Then, when we will have 13.0-P1, P2, P3, meaning we have some security advisories or ERETA, what we will do is, again, define ReproducibleBuild. We use the same source date epoch as the one we used to bootstrap. You need to set package version to make, because by default, if you make the package, it will be called 13.0-P1, and it will be called that also inside the tar, inside the manifest of the package. So, you need to use the same value as a bootstrap run. Use temporary Reproducer. You compare the package with a bootstrap run. You can just use MD5, SHA or whatever. You regenerate the package with the correct source date epoch and the new package version. And all the packages that have changed, you delete them from the original repo. You copy the new one. You regenerate the repository. And then you will, for example, only the kernel have ERETA, you will end up with just one new package, which is freeBSD-Carnal-Generic-13.0-P1. There is nothing currently in the source tree that does that automatically. This is something that I'm working on and I hope to have everything ready soon. There is still one problem with package that if you, for example, I create a new package and people just pick a G-upgrade to upgrade the system, the new package will not be installed unless it's a new dependency of an existing package. So, there is a plan to use pick a G-group. This is a feature that I am currently developing. Baptiste designed pick a G-groups a long time ago, but only on the paper. And when I'm in paper, I'm in his head. So, this is basically meta package like we have on the source tree, but at the repository level. So, when you create your pick a G-group repository, you give it a directory with a lot of pick a G-groups, and it will create fake packages that only have dependencies. So, then the freeBSD installer could just have freeBSD-bassgroup-debug-slip32 and we just select which groups that you want to install. And, yeah, since you are updating a group now, a new package will be installed automatically on updates. For example, a few days ago, maybe it was yesterday, Matthew Siemens sent a mail to pick a G-base and said, yeah, I've updated my pick a G-base system and I was missing a lot of files, a lot of package. And, yeah, this is the problem and we need to solve it with pick a G-groups. One thing that I plan to do, maybe not for the first one of pick a G-groups, will be multiple candidates for one package. So, if the freeBSD release engineering team wants to create a dash-no-manual or dash-no-capsicum package, in the group, you will have as a candidate for freeBSD-utilities multiple candidates. So, that will be the first one that is without any src.com for tweaking. And, you could have another one which is with src.com for tweak. I think it will be good, but it will be probably on the pick a G-group version too. So, current work, I have bsd install support. That means that the installer is able to install a pick a G-base installation. It's a bit crappy but I don't plan to uncrap it because I want first to use pick a G-group. So, yeah, I just made the patch so I could test that everything was working. Same thing, I have a release image support, but there is no point of committing that if the installer don't have support and the installer needs a pick a G-group. But at least it's done and I know that it is working. I've made a script called canalsedex which will allow to... So, on the pick a G-base system, when you install the kernel, it will install in slash boot slash kernel dot canconf. And kernel select is just a tool that will auto-register the kernels that you install by registering a link at slash boot slash kernel so the bootloader could find it. And it will also remove itself and fall back to a default one if you remove a package. For example, if you have installed your freeBSD 13.0 with pick a G-base and you want to test the freeBSD debug kernel, if you pick a G-install freeBSD dash kernel that's generic debug, it will auto-select it for the next boot and if you remove it, it will remove the link and use the previous one or if the previous one is not installed anymore, it will just use the freeBSD dash generic kernel. And I need to do more package splits again. So, if you're to work, I really need to talk to release engineering so we can have official package even if we say to everyone, don't use it or use it only for tests. Not having right now a package in an official repo means that people cannot really experience correctly the pick a G-base project. Yeah, I think it's bad. I still need to do a freeBSD update, a utility. Right now freeBSD update is just pick a G update, pick a G upgrade and everything is done correctly. But yeah, I need to do that in a script shell that will take exactly the same argument as freeBSD update. So if people have Chrome job or, I don't know, anti-ball or salt job that does freeBSD update, it will just work for them. I might want to do pudria-image support. So pudria-image, pudria is a tool to build package and can also build an entire image of the freeBSD system with the package that you built. And yeah, we need to add some pudria-image support, but if someone else wants to beat me to that, I will be perfectly happy. So are we there yet? Not yet, but much closer that it used to be and at least we have someone working on it. If you want to help, there's still a few bugs in the MK file. I'm honestly very surprised and very scared when people tell me that they are using freeBSD base, pick a G-base for a long time because I honestly don't know how some stuff could have worked. Right now I'm only aware of one bug in the MK file and it's not really a bad bug, it's just that some profile and debug file end up in the wrong package. So you will still have them, it's just not the right package. And if you want to test, just create a minimal freeBSD base package and install, for example, freeBSD-iSQZD and try to use iSQZD just to see if the split was done correctly, if the package contained everything and if all the dependencies are brought in automatically. I will not have time to test every package independently, so yeah, we need some help on that. And there is a mailing list, pick a G-base at freeBSD.org. Just an email, I try to read, I usually don't respond often, but yeah, I will try to do that more. I want to thank Baptiste and Glenn Barber, who first of all reviewed all my work on pick a G-base and reviewed my slide also, so big thanks to them. And now if you have any questions, I will be happy to answer. Yeah, thank you for the talk. I was interested in, when you split packages like NFS, which have kernel support, does the kernel parts go into the kernel or the package with the feature? No, the kernel part will not be split as long as the generic image defines NFS support in the kernel, it will stay like that. But all the user-land utilities will be in their own package. Okay, thank you. And same thing for every other subsystem. What about things that are kernel modules? So when I started I said, okay, I just want to have one package for kernel, but the more I do work and the more things that we should have some kernel split in. Like, there is a lot of modules that I don't care about. And if I find an elegant and easy way to generate some kernel package that only contains the kernel and splits the module into different sub-packages, maybe that would be something that I would like, but it should be done... The easy one to start there might be just all the firmware stuff? Yeah, firmware file, for example, should be in a separate package, yeah. So I should just commit quickly while nobody is really working at the package base because I'm sure that if I do something like that, it will bike shed for months and months and years and years. So my question was more about... You talked about pudrare image support. Does it make sense to build it into pudrare image if it's just for building the packages or do we need like a pudrare base, kind of like bulk, but for building just the base repo? So pudrare image support, I think the best way would be that you will not compile your gel and it will just insert the official PKG so you don't have to compile anything. Right, but what if I want to compile just the repo for a base system that's packaged? Well, you could use PKG base, so I don't touch that either. You will bootstrap your stuff, give the USB key to someone and you could automatically update it. I don't know. But please open some merge requests on pudrare and we'll talk about that. If I may have a question. So one of the things which I really liked about FreeBSD and I actually use it daily is that if you download the tar balls from the distribution from the download to untar them all, you have the FreeBSD in that directory, like the fully functional thing. So with the PKG base, will that still be possible without any... And I do that sometimes on other operating systems, like on Linux for example, right? So will I have to have a binary of PKG to install stuff in a directory or I still will be able to just use tar to create a folder full of FreeBSD? I think that we have some plan to remove the base.txz and kernel.txz tar creation. It will not make sense. Okay, but after considering we are fully PKG base and forgot about ever having non-PKG base, will it still be... I don't see how it plays well together. Like having base.txz with the package of base at the same time. Well, some people would probably want to still use them because they have a lot of CI jobs using it, et cetera. I also plan to make a script that will convert your existing system into a PKG base so we just fix the record if you have the correct file. And so you could use, for example, you could just extract base.txz, run this script and you will have PKG base system without ever running PKG install. But you are talking something way in the future and we should have a lot of stuff to do before. Yeah, that would be cool if we have that feature. Thank you. Also, the package files are just tar files, so if you ignore the... The plus manifest, yeah. Plus manifest and three other files, you can just extract all the packages into a C. And you will have exactly the same thing. My question was going to be about how do we convert an existing system, but your answer is... Yeah, so the idea of the script came up when I was talking to Baptiste and he said, yeah, but if people complain about the install time because this was when we had a high-toned road package, he said, yeah, we can just do exactly the same thing and do a script that will just create a fake PKG base system but that can be upgraded after. First of all, thank you very much for all your work on this. I think it's great that someone's picked it up and is charging it forward. So my next question is not meant to disenfranchise at all, but I just wanted to understand what your thoughts were about the true OS idea of having the package base out of source. And when I sort of saw that, I thought, that's an interesting idea. I mean, a lot of work had already been put in to getting package base in the source tree, but if I look at every other program you build, you don't put the instructions on how to make a package in the source tree for that program. You do that separately, like in the ports tree. So it kind of aligned well from that point of view of my mind. What are your thoughts on that and I guess now it's been dropped? Yeah, yeah, apparently. So, yeah, AIAC systems started a side project, a side PKG base project that used the ports tree to build the ZER package system. Split was not done the same way and I'm not going to talk about that, but they have maybe 12, 20 package. I think it's not enough. My main problem is you cannot use the port system efficiently to cross build. So, meaning that I cannot use right now the AIAC system method to cross build for MV7 or M64. That's a big showstopper for me. I have a lot of other minor concerns, but that's one of the primary ones. And I had one other question. I guess concerned with the large number of packages, which I don't agree with you. I don't care too much either, except when I download them each time I knew it starts to download the next package, there's a slight pause before the download then continues. And I started wondering how does FreeBSD update the port snap do that so quickly? And then I found that they have this thing called pipeline HTTP or PHP HTTP get, as it's called, and you can look up the man page for it. Do you know if there's any work to try and get package to use pipeline HTTP get? There is no work, but I've bugged BAPT about adding multiple download, multiple concurrency download into package and he's thinking of doing it. Each time I see him I try to convince even a little more that he should really work on that. Same thing for the installation. There is a lot of package that you could install in parallel because they do not conflict. And sometimes it makes sense to extract a lot of torque in the same place. Like if you have an NVMe drive, you can extract maybe 4, 5, 10 TGZ at the same time and it will be okay. So it's planned, I would say. But nothing is really happening. For the download side, the gentleman that implemented that I think was Colin Percival, who's next door doing another talk right now. So maybe getting BAPT and Colin to talk might be a good idea. Yeah, exactly. So what about versioning schemes and package releases? If you follow... What about upgrading and versioning scheme and patch releases? So upgrading patch releases will be... All the packages will be served on the same repository because it's still, for example, 13.0. And if you want that one-point upgrade to 13.1, when 13.1 is out, this is something that the fake FreeBSD updates script shell that I will make will handle. So it will just replace your pkg.conf, pkgbase.conf. It will replace the repository. And just update your kernel first. You fetch all the packages, reboot on the new kernel with the old base, install the new base, and there you're good to go. Okay, I was thinking more of the patch releases when it goes to P1, P2, when there's a security update, and maybe just one package is actually influenced by that. And what about what happens then? Is there anything you can talk about? Just unload the new package. Just that one package? Yeah, yeah. So if there's a bug in ZFS tools, for example, you will just get the new TPS. ZFS tools and that will have P1, and the rest won't. Yeah, exactly. So how does it comply to FreeBSD version? Will that be upgraded still then? Sorry about that? This is the FreeBSD versioning command. Okay, you have 12-1, P1. Yeah, I don't know if it's currently working with FreeBSD-Version, but I will make sure of it if it's not. And I don't see why it will not work. But I have to look. I have to look. Because really, FreeBSD-Version... The goal is to still have the FreeBSD-Version command. Yeah, but every package would actually then influence that one binary, right? Yeah, so maybe we will need to put everything related to FreeBSD-Version in its own package, and this package will be bumped at each dash P something. I don't know. That's actually a good question that I don't really thought about it. Because you have like 200 packages, you would actually have 200 versions. Yeah, yeah, yeah, yeah. Like in Linux. Yeah, I will look at that. Yeah, thank you. Thank you, Emmanuel. Thank you.
