Having recently done just that, the disklabel man page is what I used,
and it's remarkably clear on this:
disklabel -B [-b boot1 [-s boot2]] disk [disktype]
I didn't need [disktype], and boot1/boot2 are in /boot, disk is your
boot disk (mine was rda0s1a). It just worked fine, no problem, then I
was booting my elf kernel.
There are other new issues (like new flags to strip, for those that
install /var/crash/kernel.debug's) and setting up a /boot/boot.conf. A
buildworld now installs your new modules for you, and new bootblocks
also, making at least that part simpler. Those with smallish /
filesystems may want to watch this part carefully ... but lkms won't be
needed anymore, so things aren't growing out of bounds.
