Jeremy,

Thanks for the feedback.  Couple of quick follow-up comments below...

This was basically the direction we were thinking we would end up heading.  We're
biased towards what we are calling the "real" installation because the live
image is primarily a pretty installation vehicle for us.

I took a look at the livecd-creator script modules section that you mentioned and I
understand now why this is no longer working for RHEL5.  I think we can just modify that
section of livecd-creator to add the specific modules we'll need. 

It raises the question though, how should a livecd-creator user customize the set of
modules that they need installed (in a case like this one).  Obvious options would be:

1) livecd-creator command-line parameters (requires livecd-creator changes)

2) modify livecd-creator to taste on a case-by-case basis (yuck)

3) kickstart syntax (I don't know if this is really a valid option)

Any thoughts?

Thanks,

-Andy
