Kickstart-list Digest, Vol 80, Issue 4

[Lance Gropper]

Hello Joe:

This is a followup to a previous posting - I need to alter constants in the
kickstart file, which can't be altered in the %pre or %post sections. In
particular, I'm creating an automated install, however the source
installation device varies from machine to machine (on some machines, it's
sda, on some it is sdb, and on some it is the last available sd device). The
thinking here is that I can put statements in the %pre section which will
modify the kickstart file only if the system is different from how the
kickstart is currently set, then I want to rerun Anaconda at that point.
When the Anaconda restarts (or starts), if it sees that the file matches the
system, it continues with the kickstart process without modifying the file
and without restarting Anaconda. I have no problem with the logic or
modifying the file - I just need a way to restart anaconda without rebooting
the machine or rerunning GRUB. Maybe even run a second instance of Anaconda
from within Anaconda (but then clean exiting will become an issue).
