Without re-rolling the install tree, there isn't much way to

I guess this confirms that I am not overlooking something obvious,
and that what I am trying to do is "hard".
I have a script to do so, except for finding out which rpms are to be
updated. would the following approach be ok?
- install a system manually, do whatever yum update/remove/install
- do rpm -qa to get the list of installed rpms
- if they are on the CD, copy them
- otherwise, download them
I'll stick with my current method of doing a "yum -y update" in the
kickstart %post, and I may investigate the suggestion of using VMware
snapshots (although that doesn't quite accomplish what I am trying to
do).
What I've found that works fairly well is to do the following steps:
1. copy the DVD installation tree from the DVD .iso to a working directory
2. copy available updated RPMS (typically with "rsync") from a mirror
site into the CentOS/RPMS directory
3. use the "repomanage.py" utility from the "yum-utils" package to
remove superseded RPMs (with the "-o" argument):
repomanage.py -o <base>/CentOS/RPMS | xargs rm -f
4. Regenerate the hdlist file on the DVD image (requires the
anaconda-runtime package to be installed):
/usr/lib/anaconda-runtime/genhdlist --productpath CentOS <base>
