That I misunderstood things and forgot about the "rebased sometimes in
intermediate places" aspect I once knew about. Sorry. I'll leave the
text as it is then.

Nevertheless makes me wonder: is that strategy wise in times when some
ordinary users and some distributions are building kernels straight from
git repos instead of tarballs? I'm one of those, as I distribute
stable-rc packages for Fedora here:
https://copr.fedorainfracloud.org/groups/g/kernel-vanilla/coprs/

And the "rebased sometimes in intermediate places" aspect complicated
things for me (my scripts handle that and apparently I forgot about that
since I wrote them; uhhps :-/ ).

But whatever, not that important, feel free to ignore this remark. And I
can see why you are doing it the way you do, too.

Thx for you helpful feedback!

Ciao, Thorsten
