Well, I did it … and, so far (knock wood), it’s working ok.
What I did was: Upgrade my Redhat Linux 8.0 system to Fedora Core 4.
Last time I tried this it went horribly wrong … there was some kind of problem with the system that caused all available memory to be eaten up like it was going out of style … and then it started chewing on the swap space … to the extent that there was no memory and no swap space available.
To add insult to the injury … my backup procedure wasn’t as solid as I had hoped.
The end result was that my system was down for about 2 days while I recovered manually.
This time, however, I had a absolutely fool proof backup plan.
