That's because I didn't know how to get it, since I have no access to SuSE. I
am very new in Linux, as you have surely detected.

In the interest of saving time, which is at a premium right now, if I can
retrieve a few things that are not backed up, I think it might be best to just
reinstall v10..3 from scratch. I have a Ubuntu v6.06LTS disk, and as I
understand it I can boot with it, and gain access to the /home directory where
those small things reside. Or I could do the same with a Rescue boot from the
10.3 DVD. Can I impose on you, or Joe, or anybody else, to let me run past you
the actions I need to do to accomplish the retrieval of these files?

Joe Morris gave me some hints about using Rescue for a different purpose:

*****

> > mount -o bind /proc /mnt/proc
> > mount -o bind /dev /mnt/dev
> > mount -o bind /sys /mnt/sys
> > cd mnt
> > chroot /mnt
*****

That was for using YaST. Which of the above "mount" lines are necessary for the
different purpose I have now?

Now I want to access the /home directory and also a JFS partition that I use
for transfer between SuSE and OS/2. In normal SuSE operation, that partition
is,  "/mnt/transfer", so I would add the line "mount -o bind /mnt
/mnt/transfer".  Have I generalized correctly from Joe's notes?

I would also add a line like "mount -o bind /home /mnt/home", which would cover
any subdirectories. I would copy the needed files. Being root, I would not have
to deal with permissions.

Is all that correct? 

so I would add another line to the above as follows: <mount -o bind /min>

Thank you for the advice below. I will apply these hints when I reinstall the
OS.
