Yes -- if you apply patches or you use cvsup(1), you get updated
source code, which you've got to compile and install -- either the
whole system or just the parts affected by the patch.  This seems
alarming to the uninitiated, but once you've done it a few times, it
becomes routine.

On the other hand, check out the security/freebsd-update port and it's
associated web site at http://www.daemonology.net/freebsd-update/ --
this isn't an 'official' part of FreeBSD yet (surely only a matter of
time, though).  This is a very interesting system for generating
minimally sized binary patches that can be applied directly to a
system without requiring a compilation step.
