Ok, that's good to know.  I thought I had tried that before, but perhaps
not.  I've solved this for now for myself.  Instead of muck with
anaconda's eccentricities, I engineered out the problem.  

What I'm doing instead is appending a parameter to the PXE boot line
that means nothing to any part of the installer ala:

destip=<ip>

Then... a simple non-chroot post-install script passes this into the
chroot environment..

cat /proc/cmdline | tr ' ' '\n' | grep ^destip | sed 's/destip=//'
> /mnt/sysimage/root/ipaddr.install

Then without the gory details, I'm essentially using that IP to make
modifications to the key config files during post-install.  Such as...

Add entry to /etc/hosts
Mod /etc/sysconfig/network
Mod /etc/sysconfig/network-scripts/ifcfg-<intf>

So... with the common network config pre-filled in the kickstart,
anaconda uses the IP from DHCP to do the install and I clean it up at
the end.

Probably not super-elegant, but it makes my admins only have to dink
with one variable in the PXE boot menu when they select the kickstart to
use.

Thanks!
