Here's a bare bones kickstart method (not Kickstart[tm] per se):

Regarding kickstart, among choices for pre-scripted installers it is one
of many. I personally favor the likes of SystemImager, even though it's
not quite in the same category (FAI is though, IMO). Even dd with netcat
is pretty powerful for homogeneous nodes.

Once you've chosen your distro based on experience/need, there are
usually a few ways to put it on your spindles.
