Description Thomas Vander Stichele 2007-04-20 19:28:10 UTC
Description of problem:

I had a post script that downloaded a setup script then runs it.  This script
installs an rpm, then runs a script from that rpm.  However, the script could
not install the rpm because it claimed it wasn't there.

Further inspection leads me to believe that:
- a post script gets executed inside the chroot (at /mnt/sysimage)
- its cwd is the real /, and not the chrooted /

This is evidenced by the fact that both the downloaded script and the rpm ended
up in /, and not in /mnt/sysimage where I expected them.

I used the same mechanism on FC5 without problems.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Created a ks file
2. use this post script:
echo "one" > post.log
echo "two" > /root/post.log
3. install machine with ks file and check on the console
Actual results:

after completion of post scripts but before rebooting, machine has /post.log and

Expected results:
should have /mnt/sysimage/post.log and /mnt/sysimage/root/post.log

If it matters, my install was done over PXE, with vnc enabled.
