[K12OSN] Upgrading 4.4 wipes /etc/dhcpd.conf

[R. Scott Belford]

I recently read a post about an upgrade wiping dhcpd.conf.  It happened 
to me yesterday on two boxes that I upgraded.  I am about to have to 
deliver new dhcpd.conf files via floppy.

The scenario on both boxes: running 4.4.1 on an amd opteron, 4 gb ram, 
10k sata drive.  I ran yumex, refreshed the package list, and installed 
the updates.  The clients stopped working.

I checked repos, saw that k12ltsp continues not to remain checked off, 
selected it, and refreshed the package list.  Now there was a dhcp 
update from the k12 repository.  I was relieved that help was a download 
away.  This did not fix the problem.

Both servers now have a blank dhcpd.conf file.  There is no backup, no 
rpmsave file, nothing.  Running 'updatedb' and 'locate dhcpd.conf' does 
not reveal a misplaced file.  The update simply breaks the installation.

Heads up.  4.4 issues persist, and Open Office still opens slowly.
