This is not correct, and this is not what 19.4.1 says.  The correct
procedure is as Mike Schultz described.  Please review that section of
the handbook.

If you did, indeed, do as you described, then you have a world that's
out of sync with your kernel.  Try this:
1) Boot in to single user mode
2) fsck
3) mount -a
4) cd /usr/src
5) make buildkernel
6) make installkernel
7) reboot

If you're unable to complete those steps, then you may be better off
reinstalling and trying again - write it off as part of the learning
process.  There are ways to restore your system if you've made this
mistake and the above doesn't work, but it's rather advanced stuff.
