Thanks, everyone, for all your help.  I think the ". 
/etc/sysconfig/network" is especially neat.  I ended up waiting to run 
cfengine until reboot, as follows (from kickstart file):

%post
# [...]
# FIRST BOOT
mv /etc/rc.d/rc.local /etc/rc.d/rc.local.sav
cat <<"RC_LOCAL" > /etc/rc.d/rc.local
#!/bin/sh
/usr/sbin/up2date --solvedeps=wfu-cfengine
mv /etc/rc.d/rc.local.sav /etc/rc.d/rc.local
RC_LOCAL
chmod 755 /etc/rc.d/rc.local


On first boot, /etc/rc.d/rc.local is evaluated as above.  The RPM 
"wfu-cfengine" automatically runs "cfagent -Kvq" in *its* post section. 
 (We have a RHN satellite server so we can upload our own RPMs to 
up2date, but a yum repository would work equally well.)  rc.local then 
deletes itself by moving the original.

I did this because our cfengine setup runs some iptables stuff, and it's 
more convenient to run in the actual OS (with all modules, etc. set) 
than in the bare-bones kernel used by kickstart.

Yours,
John
