This should be fine.

Since you've built a custom kernel you may want to keep a copy of
your kernel build config ("LINT") file, eg. /usr/src/sys/i386/conf/HOSTNAME.

Note that you can't use freebsd-update to patch a custom (non-GENERIC)
kernel.

You can restore the kernel source code by extracting the ssys.??
binaries (normally found in the /src/ directory, eg.
ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/7.2-RELEASE/src/ )
using install.sh (found in the same directory).  Probably also with
sysinstall, but I don't recall the steps to do that.
