I agree, Kickstart should not be the_ only_ file for configuration.
Actually I sort of argued both sides of that coin. And I ended up
changing my mind. What sorts of option and configuration do you think
should not be in kickstart, but somewhere else?

Why only LiveCD, think beyond the liveCD. Eg. Small systems can be fit
on to a USBstick, Rescue systems, small network servers, small streamers
usbstick (especially with livecd-iso-to-disk) is really just an
alternate form of livecd.
But yes, the changes I proposed to mayflower can also be used to
generate initramfss that are useful as rescue systems, and perhaps even
as entire-system-in-initramfs for small servers/routers. I never
suggested it was useful for livecd only.

It is a must have feature. But again this should be configurable.
Currently Which I developed is doing a persistence at the time of
instalation(again a bit hard coded).
I'm still curious where this implementation you speak of that you claim
was posted to this list is. Please repost or give a link to an archive
I'm curious whether your implementation has design aspects that are
better than the implementation I posted a couple weeks ago, and
discussed at length on this list in the couple weeks before that.
(as I've told Tim offlist, I'll be posting an updated version of that
implementation within the next couple of days. I'm just honing my git
skills at the moment)
