Kickstart-list Digest, Vol 59, Issue 5

I've found that with the bash shell from busybox used
during the kickstart doesn't have all the functionality one
is used to. And it varies between rhel3,4,5. So I elected to do any
scripted partitioning in a python script.
Following are the %pre install script and autopartition script pulled
from the server via NFS to accomplish our install. (NFS server IP
address is 192.168.0.2). Part of the python code from the autopartition
script was borrowed from /usr/lib/anaconda/list-harddrives-stub.
I rely heavily on the %include capability and have made stuff
very modular. I utilize a perl script that creates our ks.cfg files.
Hope this gives you some more ideas.
