Compiling FreeBSD kernel - part 1 of 4

Logging in to my FreeBSD server using SSH, and compiling a new kernel. I didn't make too many changes, it was just a test to make this video. To record the screen and split the video into four files, I used xvidcap and avisplit on Arch Linux.

Newbie question... how does the new build supplant the previous kernel that's active? Maybe a reboot, then the boot loader finds the new kernel?

@WinterXL Hi there! After the new kernel is build, you can install it by using the command "make installkernel KERNCONF=newkernelname. When the install is completed you have to reboot the machine, the new kernel is used. If something goes wrong, FreeBSD has options to use the previous kernel.

If you follow the handbook on "building and installing a custom kernel", nothing can go wrong!

Enjoy BSD!

If you have a multithreaded/multicore architecture, you should gain benefits with make's -j option :)
