Re: IP address.
Ask the proc filesystem?  I think it's mounted by then.

Re: %post section
JimD normally had it do a retrieval from the dhcp server itself (you can
use the first resolver too;  either way, these are something you get
handed and therefore can parse back out of the running config quickly)
which allowed him to have it honor custom URLs with extra bits.  The
glorious thing is that it moves the sysadmin controls back to the server
where it belongs instead of floating around on a scraggable floppy and
falling out of date.

You could also set the thing up to serve kickstart via PXE - JimD was
demonstrating that at December's BayLISA.

We'll be at BayLISA tonight, maybe we can chat more there.
