Post install scripts run in a ramdisk environment. The filesystem for the ramdisk environment, for RH 7.1, is in the RedHat/base/stage2.img file, on the first CD. Copy the stage2.img file to disk, and do: # cd <to a directory where you want to mount the stage2 filesystem> # mkdir stage2 # mount stage2.img stage2 -o loop # mount stage2 using the loopback device # cd stage2 # ls # this is the "root" of the ramdisk # cd usr/lib/anaconda # cp <the directory where smp.py lives>/smp.py smp.py # see NOTE, below # chmod 755 smp.py # cd <back to where you mounted the stage2 filesystem> # umount stage2 NOTE: I put my extra python scripts into the anaconda directory, along with the other python scripts which anaconda uses. You'll have to add /usr/lib/anaconda to your PATH in your kickstart post-install script. Or, you can put the script in one of the other directories used by default by post-install scripts. And, no, I don't remember that PATH off the top of my head; I think it includes /bin and /usr/bin. Now that you have a modified stage2.img, to use it, you'll either need to re-burn the CD, or do an over-the-network install. For burning a RedHat CD, start with: http://www.linuxdoc.org/HOWTO/RedHat-CD-HOWTO.html That document may be getting a little out of date, though. For over-the-network installs, there have been previous articles on this list about how to do a network install, how to consolidate CD1 and CD2 into a single directory, and so on. --Seth Alford setha@xxxxxxxxxxxxxxxx On Fri, Feb 08, 2002 at 10:00:44AM -0600, Rebecca.R.Hepper@xxxxxxxxxxx wrote: > > Thanks for all the ideas on how to tackle this problem!! > > My plan is to first try out the suggestion below.
