But I was talking about the technical backgrounds. For me as an end user (on amd64 actually) it is just too risky to update my server and have to be afraid every time it could break.
On amd64, you are using pure Debian. Debian is one of the most stable distros in the world. If you are worry that much, that is being overly paranoid. You should have an identical test system to test updates on and be testing backups/restores. I have servers that are used by almost every employee at a large enterprise and I worry less than you do about your OMV box.
Did Volker consider to use some other base like Buildroot?
I know what it does but I fail to see how it would've helped this situation.
