F41 is EOL in a few days. So I upgraded using the dnf method, as usual.
Warning! If you have 2 different architectures of some rpms installed,
which is likely if you use WINE, then a bug may trigger where the
migration from separate /sbin to combined /bin & /sbin doesn't work
properly. It will leave you with a decent mess to contend with.
Probably the best idea is to find all those other-arch rpms and dnf remove
them first. Then run the upgrade. Then reinstall the other-arch rpms.
Obviously you'll need to record what rpms those are.
Hopefully the bug won't trigger on "normal" installs without 2 arches... I
will find out soon.
