%post section of Fedora8 kickstart install doesn't run
I've used kickstart pretty well to do most of the installation of Fedora8, but I'd like to do a few things in the %POST section, but I can't seem to get it to work. Specifically, the commands in the %POST section don't get executed. I've edited the .cfg file with system-config-kickstart, so I don't think there's a syntax problem. The relevant section of the .cfg file is:
mount -o nolock 184.108.40.206:/usr/network /usr/network
open -s -w -- /usr/network/scripts/fedora-client.script yes
Even the first command, to make the /students directory, doesn't happen. That is, when I go to the machine after kickstart completes, the directory doesn't exist. I've looked in /root/install.log and /root/install.log.syslog, and I see no errors or other notations. I've looked in /root/anaconda-ks.cfg and the same %post section is there, so it seems to have "read" the commands.
Any ideas what I'm doing wrong or how to debug this? I'd be happy to post the entire kickstart file if necessary.
