Resend: Anaconda modifying network files

[dwight at supercomputer.org]

One thing to watch out for is kudzu. I ran into a similar situation a 
couple of weeks ago, with kudzu overwriting the ifcfg files and 
changing them away from what the %post section was doing, right 
after the %post section had completed, and before the system had 
rebooted.

That is, kudzu will apparently do some final manipulations after 
the %post section has run. There doesn't seem to be anything one can 
do about this either.

Note that kudzu is a fundamental part of anaconda/kickstart. You 
simply can't remove it. RedHat defines an absolute minimal 
installation as consisting of kudzu (and not coreutils + kernel, 
which one would expect).

One can get around this limitation by creating the equivalent of 
a .firstboot in /etc/rc.d/rc.sysinit, which corrects things when one 
first boots up.

Hope that helps.
