Loren, I'm pretty sure that with a 2.2.16 kernel it's the "SUSE 7"
system that actually predated SLES 7 in the s390 world -- might even
be the 6.4 "beta", eek!  :)

Pre-SLES8 systems used /etc/rc.config to configure everything
except routing information.

The three files you need to update are:

/etc/rc.config
/etc/route.conf
/etc/hosts

There are a couple of others that have to change if the host name
changes, but if only the IP address and gateway are changing, these
are the ones.

In those early releases, changes to /etc/rc.config don't take effect
until after you run "SuSEconfig".  I think that SuSEconfig also
manages /etc/hosts (but maybe that's just on later releases), so I'd
suggest making what changes need to be made in /etc/rc.config, run
SuSEconfig, and see what else needs to change.

Make sure that *somewhere* you update your default gateway address.
I think that's elsewhere in /etc/rc.config, but might be in /etc/
route.conf.

You can use the mount-the-copied-disks-to-a-running-system method,
but you will need to mount all the copied system's disks -- at the
right mount points -- and chroot into the copied system in order to
run SuSEconfig.  Example:

mount /dev/dasdk1 /mnt/copy
mount /dev/dasdl1 /mnt/copy/usr
mount /dev/dasdm1 /mnt/copy/var
chroot /mnt/copy                # <-- all file accesses are now from the copied
system's disks
vi /etc/rc.config
SuSEconfig
exit                            # <-- return to your running system
umount /mnt/copy/usr /mnt/copy/var /mnt/copy

Replace the DASD names with the actual names you get on your system,
of course, and don't forget to detach the disks from your running
system when you're done.

Cheers,
Vic Cross
