[CentOS] Minimal kickstart.cfg requested

Hello, all.  

I'm looking at building about a dozen CentOS VM's for a project.  I have
a desire to use kickstart for this coupled with PXE.  I'm looking for a
minimal ks.cfg file specifically, I want the bare minimum of software
that is needed for a system to function.  I will need sshd and yum as
the only 'services or applications' on top of the OS.  Does anyone have
an example I can work with, or suggestions on getting to this minimal
configuration? I'm just looking to save some time, rather than
re-inventing what may and probably is already out there.

Thanks

Daniel
