[K12OSN] /etc/ltsp/dhcpd.conf must NOT be a symbolic link

I just installed the most recent LTSP on RHEL6.1, and everything went fine,
except that ltsp-dhcpd would not start.

After a lot of head scratching, I finally looked at /var/log/messages
and discovered a "permission denied" message for dhcpd.conf.

My practice is that I never change files in /etc, because I try to cut down on
the size of things that need to be backed up. Rather, if I want to change a 
file, I put a copy
of it in /usr/local/etc, which does get backed up, and then make a symbolic
link to it. Rebuilding a system from scratch is as simple as recreating those
symbolic links (a very small number) when a system is restored from backups.

In any case, simply copying this file back to /etc/ltsp fixed it, and my thin client
booted up and started ltsp flawlessly.

It might be a useful tweak to ltsp to allow files to be symbolic links. Not sure
why it didn't like the link.
