Yes, I know. German title in the English forum… Sorry!
Well, the saying in English doesn’t quite do it: “There’s life in the old dog yet.” On Friday I killed the “old dog”. 
I really though it was dying just three years ago. Lack of time just let me keep it going, the disaster never happened. It just did its job. But doomsday is closing in. EOL of Leap 15.6 and end of support for baselevel-x86_64-v1.
So, I went to the hardware store next door. I’m very lucky having a hardware store as in “building centre” as well as in “computer online distribution centre”, both in walking distance. I got a shiny, new, not-too-fancy Asus Prime A520M-A II with a Ryzen5 5600GT. Should be just fine for the next 17 years. Legacy boot is available so I don’t have to reinstall - at least not now. First things first, change BIOS settings to switch off all that Redmond stuff and being able to boot from what would be sda.
The hardware operation went smoothly, software-wise almost so. Out of my own ignorance I forgot about my ATARaid. It’s the data store for the users in my home network. The raid was listed in fstab and could apparently not be found. Where did I have to end up? In emergency mode, where else?
Emergency mode is so intimidating, as there’s so many things not working. Network, for instance. I knew I could have avoided emergency mode by commenting out the related line in /etc/fstab. I forgot about it before, now I had to make do with vim. I was never friends with it, but eventually I managed to edit the file. So, I got the system up and running. Setting up network manager to eth1 was easy.
Only other issue, now I had two ssd with “unknown filesystems”. Again, my ignorance. I just didn’t care/know that the raid disk are of no use in a system without the raid controller.
So, I just restored the data from my backup. Never had to do that, before. It was very easy with unison. I could just use the backup profile as template and change the direction via the “force” option. The second disk is now mirrored once an hour via unison as cronjob. Aside from that, no other issue occured. I could just continue using the installed system without any software change.
Don’t get me wrong I don’t want to boast about all that. I know it’s very average achievements. I just felt the need to give a follow-up on my old thread.
And I’d be curious if that could be done with that mainstream operating system from Redmond.
However, all this was due to prepare the next step: Upgrade to Leap 16. I was always a late adopter.

Sounds like Slowroll might be up your street as you say you are a late adopter & save all the bother of upgrading every few years. 
@jjis , I’m actually thinking about it. Probably I should test it out in a virtual machine. It’s all just a question of time…
