Thank you! Makes me wonder how the generic kernel entered my system,
then, but not enough to investigate! I'll just remove the generics...

As for upgrade vs fresh install I never managed one successful upgrade
(OK, maybe I tried just twice ;-) ) so I prefer the fresh install.
Though I've broken a bone or two by leaving all the config files on my
home partition and then installing on the root partition. WOW, can it
break things...
