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
