After running with SUSE 10.1 for a while I've decided it's time to

Firstly, having experience of upgrading many different systems with many
different OSs I would not even consider starting without thoroughly
backing up configuration and user data.

I do a full backup as first step.

An upgrade can be a very exotic
way of turning your machine into a potential paperweight, and one should
have a route to get back to where you were before you started before you
start.

Absolutely. I only hosed one upgrade, from 7.3 to 8.1, because yast2 (7.x
used yast1) forgot to mount extra partitions (/opt, I think) and run out
of space in mid-upgrade. Disaster! Yast did not calculate the space
needed, gave no warning.

Next time I learned to check and mount manually if necessary.


I admit to be being surprised about the partitioner attempting to
rebuild the partitions. Did you select upgrade/update an existing
installation? This usually leaves the current partitions alone. If it
cannot find the existing installation there is something very wrong.

The thing is that, although he mentions "upgrade", he is in fact doing a
fresh install, wanting to leave /home unformated (I left the original
paragraph above: I guess you misunderstood slightly). This needs
entering the manual or expert partitioner mode.


I am just going through the process of upgrading a box from SuSE 9.3 to
10.2 now....

I did the same. My 10.1 got trashed in a disk crash just before backing
up, so I restored 9.3 and upgraded to 10.2. Went fine O:-)


I have so far found that the following got torched.....

syslog (configuration file deleted)

Not really. There has been a change, and /etc/syslog-ng/syslog-ng.conf.in
got removed, yes, but I think /etc/syslog-ng/syslog-ng.conf remained.

Anyway, yes, a lot of configuration files get deactivated, renamed to
*.rpmsave or similar, and you have to check the output of
"rcrpmconfigcheck" run, or the output of and review one by one all
entries. I prefer that to doing a new install.


Without such a backup in place this process of restoring functionality
would be much more difficult.

Absolutely. It is a must, be it upgrade or fresh install.

BTW I wish that a list of discontinued applications was available so one
can access the impact of an upgrade beforehand.

Yes.

There is another problem, if you use the downloaded dvd versus the bought
one: there are many apps that are missing and you have to install from the
ftp repo. Theoretically, Yast should be able to add a secondary source
during the install/upgrade phase, but this fails: at that point of the
install/upgrade the network is down. Yast has not even loaded the ethernet
drivers. I typed the url to be told some crazy error, just because the was
no network. Too bad.
