Trimming up our ks script

[Mike McGrath]

I'm working to trim up our kickstart scripts to make them include far
fewer packages.  This is bound to cause problems during our transition.
Our current puppet configuration probably assumes packages are installed
that will no longer be there.  We'll have to explicitly define these needs.
Initial tests show significant savings though.  On the xen servers its
over 200 packages fewer.

Just keep an eye on things as we rebuild some infrastructure and migrate
to our new xen servers.
