 I'll go back to the container OS part once more because I've talked to CentOS folks and Fedora folks also and since Fedora and CentOS is kind of upstream to REL. Right. So what is who is going to be upstream for Red Hat Core OS? So the original container Linux right before we made any integration that community that code base will still remain open source there are still non-core OS maintainers that we're working on that so we don't want to disrupt that community we'll still see core OS engineers you know keeping that going because there will be innovation that continues to happen around immutable right. We'll take those you know we'll work in that community we'll take those learnings we'll put those into Red Hat Core OS. The Red Hat Core OS and so now we based off the Fedora kernel we'll see you know work you know kind of core OS work going on in that community as well and bringing those learnings overall to the Fedora community right. So you know over time you know we always talk about the importance of the operating system but there as we get into more fast-moving environments like you know people want better ways to operate them you know they want to deal with them it's mutable they want to deal with updates and so forth so I think we're going to see a lot of cross learning between these couple of communities just there's learning in the immutable community that it's going to get exposed to the Fedora community that we think is going to be really good we're you know sort of new ideas refreshing of ideas. But this doesn't look very structured the way Red Hat has things are still like you know CentOS is there Fedora is there so. Well there's a very structured way between you know Fedora is sort of the. I mean Fedora has sponsors communities fully community driven but it's very sponsored and funded by Red Hat. So what will happen to the Kuru is the continued Linux community because right now you're saying a lot of non-Kuru developers are there. Yeah so we'll still support that community and endorse that just like we have Fedora you know if it continues to grow that's great and we will continue to support and endorse the Fedora one as well so you know for us this is an opportunity there's a realization that managing Linux host is evolving the entire market's not going to go in one direction or the other just lots of things so we want to make sure that fundamentally we know how to work in open source communities we have no plans to change that. We we still believe that the operating system is very important it's evolving and changing so we want to make sure we're actively involved with that. And we've learned through a number of acquisitions and some good and some bad like you don't want to do harm to an existing community. And so you know same way that we're not going to leave any existing tech tonic yeah we're not going to leave we're not leaving any existing tech tonic customer behind right we're not going to leave a community behind either.
