You can start with building a box the way you want it and using the
anaconda-ks.cfg file in root's home directory as your initial ks.cfg file.
In the ks.cfg file can you can also execute both pre and post installation
scripts.

After that, "google" how to create a custom RHEL or CENTOS Linux ISO. It is
not difficult to do at all.

Yea I've gotten that far, I'm more curious if anyone knew a good up to date
guide, since the best one I found was for centos, but would assume there are
some deviations between the process with that and RHEL.

Thanks, those links will be useful. I'm going to give RH cluster a try.
It seems to me that the HA-LVM implementation uses LVM tags and the
volume_list feature of LVM to implement the exclusivity I was looking
for. Clever.
If for some reason RH cluster won't work for me I can probably use the
same trick to create reasonably newbie-proof manual failover scripts.
Thanks to everyone for their help.

If it works for CentOS it's gonna work for RHEL.
