Thank you, Alf!
I am now able to get this working using your examples. Here is how i'm
doing it:
# section from kickstart file:
%pre
mkdir -p /tmp/sshkeys
mkdir -p /mnt/oldroot
mount /dev/hda2 /mnt/oldroot
cp /mnt/oldroot/etc/ssh/ssh_host_* /tmp/sshkeys
umount /mnt/oldroot
%post --nochroot
cp /tmp/sshkeys/* /mnt/sysimage/etc/ssh
%post
# other chroot stuff goes here (patches, other rpms, etc...)
(/dev/hda2 is our root partition on all our kickstarted PCs.)
I did discover that if you use both a "%post" and "%post --nochroot"
section, the "%post --nochroot" section apparently MUST come before the
"%post" section. It did not seem to work when I had the "%post" and then
the "%post --nochroot" after it. (This is only if you have code that is
needed in the nonchroot and chroot environments.)
Thanks again everyone for the suggestions.
Jeff

That does not work.
In your chroot-ed %post section you only see your new system.
The solution for your problem are two %post sections: your original
one and the new with "--nochroot". Kickstart will execute them both.
