This works, but it is not safe. The documented procedure is:
# make buildworld
# make buildkernel KERNCONF=mykernel
# make installkernel KERNCONF=mykernel
# mergemaster -p
# shutdown -r now
reboot to single user mode!
# adjkerntz -i
# swapon -a
# mount -a -t ufs
# cd /usr/src
# make installworld
# mergemaster
# reboot

The added reboot allows you to confirm that the new kernel is OK before
installing the new system. If you have installed world and then cant
boot the new kernel, you might being very bad shape, depending on what
has changed between the new and old system.
