While you can do a great many things in FreeBSD, this one is NOT a good
idea. The point of the reboot is to load the new kernel and make sure
it will boot before installing the world. an 'fsck -p' takes about 2
seconds and 'mount -a -t ufs' takes a bit less.

Once you have installed world, if the new kernel won't work you system
might not run properly with the old kernel and backing out the world
install is a major pain.

The instructions in UPDATING were written to provide a safe, fairly
easy way to update a system. Think carefully of what you are doing
before diverging from them.
