OK. I managed to beat the machine into submission. But a slight incertainty remains.

That is my problem: Did that step of the "upgrade" leave the rpm-database in a state that is not in tune with what is actually on the disk

The problem was that the centos-release was removed at the start of the upgrade (and that is needed by yum to determine which $releasever to use)

By manually reinstalling the rpm.rpm and some other packages I managed to kickstart the upgrade again (and it seems to have succeeded)
Only problem: in the second upgrade run less packages were listed as due to be updated (roughly a half). So I'm not sure: Are they marked as upgraded in the rpm-database but in reality there are the old versions on the disk.
Is there a way to say: "Hey RPM, have a look whether really the files in your database are on the disk)" ?

That question remains. But it is academic

As I said: solved
Thanks for listening
