Today I also discovered that doing something like this in a '%pre'
section is a bad idea, as centos6 waits until all pre scripts are
finished before moving on to steps such as mounting the system image
(see the problem there?).

Apparently the better way to do this is to have the above stanza be in
a first %post script with the --nochroot flag like so:


- ----------------------
%end
#end of packages

#start of first %post
%post --nochroot
#!/usr/bin/bash
while : ; do
     logger "sleeping for kickstartfiles mount to be available"
     sleep 10
     if [ -d /mnt/sysimage/root ]; then
         cp -a /tmp/foo /mnt/sysimage/tmp/foo
         # store the installer args
         cat /proc/cmdline > /mnt/sysimage/installed-version
         logger "Copied kickstartfiles to system"
         break
     fi
done &
%end
#end of first %post

#start of second post
%post
echo "this is run inside the new installation's chroot"

#<snip> remainder of your %post script

%end
- ------------------------------------

Hope that helps...
