%post problems via CDROM to VM

[gene huft wachovia com]

My shell code in the %post section of
an all-CDROM-contained kickstart does not work the same as it network build.
I'm still troubleshooting, but it appears I have a severly restricted shell
environment during this phase. (Why would it be different from network
install? same code?)  

Is it possible the %post section really
does not kick in until after it's first reboot?? If so, that may be the
difference, because I must manually, unmount the virtual CDROM after the
first boot, or it will simply boot from the CDROM again & repeat all
over. However,  I do see the message that says it's doing post installation,
but it's definately not working as expected.  

My new RHEL 5.1 32-bit VM is indeed
installed, but with NONE of the post script stuff.

I set up some echo statements to help
me troubleshoot...note that it does not create a mount point like I tell
it, and certainly does not copy off script:

-------------------------------------------------------------------------------------------------
%post --interpreter /bin/bash
#
echo "Entering into %POST section"
>> /opt/POST.txt
#export METHOD=NETWORK
export METHOD=CDROM
echo "METHOD=${METHOD}" >>
/opt/POST.txt
export VER=RHEL5_32
echo "VERSION=${VER}" >>
/opt/POST.txt
#####################
mkdir -p /cdrom
/bin/mount -t iso96660 -o ro /dev/cdrom
/cdrom
#
mount >> /opt/POST.txt
echo "Copy and execute post configure
script." >> /opt/POST.txt
#
cp /cdrom/third-party/rhel_post.bash
/opt/rhel_post.bash

ls -la /opt >> /opt/POST.txt

[ -f /opt/rhel_post.bash ] &&
cd /opt;./rhel_post.bash||\
echo "Trying just copy from third-party...not
/cdrom/third-party" >> /opt/POST.txt

cp third-party/rhel_pst.bash /opt/rhel_post.bash

ls -al /opt >> /opt/POST.txt
-------------------------------------------------------------------------------------------------
What's weird, is that it produced an
/opt/POST.txt?   file and a /opt/POST.txt file:

cat POST.txt?

Entering into %POST section
METHOD=CDROM
VERSION=RHEL5_32
/dev/root on / type ext3 (ro)
Copy and execute post configure script.

cat POST.txt
Tyring just copy from third-party..not

Any ideas?
