I keep posting this because people keep building new systems in a
dangerous way.
Doing the installworld before building and booting the new kernel is
very risky. It will almost always make no difference, but, on the
rare occasions when it does, it will leave you with a VERY sick
system and the only way out maybe to re-install FreeBSD from scratch.
While there are a few niggles, the proper sequence is:
mergemaster -p (This is NEW!)
make buildworld
make kernel KERNCONF=your_kernel_conf_name
REBOOT into single-user mode! (This does not mean drop to single user.)
fsck -p
mount -a -t ufs
cd /usr/src
make installworld
mergemaster -i (-a is a bit inadequate unless you go back and clean up
the mess it often leaves before going to multi-user
mode.)
exit (to multi-user mode)
