Right, there seems to be some inconsistent usage here. Ideally we should go
through the VFS, but given the precedence it's understandable if you don't make
it in this patch.
AFAIU, this drops support for SLES10 and I guess that this would also be true
for SLES9? It seems that the checking could be improved a bit by checking the
digits (as in the distros above)? Also add a comment explaining why.
