Is it required to have "--nochroot" in my "%post" section? I have a lot of
other things in "%post" and am not currently using "--nochroot". I thought
I should still be able to see the /tmp/ssh directory created in the "%pre"
section, correct? It does not seem to work, though, since I do not see the
/tmp/ssh directory in the "%post" section. I did an "ls -la" on /tmp in the
"%post" section, and the only thing there was:
total 12
drwxrwxrwt 2 root root 4096 Dec 2 10:48 .
drwxr-xr-x 21 root root 4096 Dec 2 10:48 ..
-rwx------ 1 root root 157 Dec 2 10:48 ks-script
I would think I would at least see the directory since it should have been
created with mkdir in the %pre section. Is this a different "/tmp"
directory in the %post section than what was used in %pre?
Any ideas?

Here is what we do. It avoids the rather ugly loop in the %pre section
to copy the data back.
-- Alf.
%pre
mkdir -p /mnt/oldroot
mkdir -p /tmp/ssh
if [ -b /dev/sda ] ; then
disk="/dev/sda"
else
disk="/dev/hda"
fi
mounted=""
for i in `/usr/sbin/fdisk -l $disk | grep -i linux | grep -v swap | cut -d"
" -f 1`
{
part=`/usr/sbin/e2label $i`
if [ $part = "/" ] ; then
mount $i /mnt/oldroot
mounted="true"
fi
}
if [ -d /mnt/oldroot/etc/ssh ] ; then
cp -a /mnt/oldroot/etc/ssh/ssh_host_* /tmp/ssh/.
echo "Copied old ssh keys"
else
echo "No old ssh directory found"
fi
# Add other stuff here that needs to be copied
# like Kerberos keytab files etc.
if [ -n $mounted ] ; then
umount /mnt/oldroot
fi
%post --nochroot
if [ -d /tmp/ssh ] ; then
mv -f /tmp/ssh/ssh_host_* /mnt/sysimage/etc/ssh/.
mv -f /tmp/ssh/*srv* /mnt/sysimage/etc/.
mv -f /tmp/ssh/*keytab /mnt/sysimage/etc/.
fi
