this affects both of them...)
I can see the advantages of this, but the COPR plugin for DNF will
need to be adjusted for this case. It currently treats systems
detected as "Fedora Rawhide" or "Mageia Cauldron" as a special case
where it will check for fedora-rawhide-* or mageia-cauldron-* chroots,
respectively.
If you change it to always be release versions, then this will
completely break, as there will be no more "rawhide" or "cauldron"
targets. Instead, we'd have Fedora 26 and Mageia 7 (assuming Cauldron
has become Mageia 7, which it hasn't yet).
At least from the Fedora point of view, such a change might be
somewhat painless, since right after branching, we increment the
release version.
Historically Copr lagged behind after Fedora branching (e.g. after F26
was branched, it too several days until the F25 was enabled in Copr
unless I am mistaken), that would mean that during the mean time, my
Rawhide updates will get broken, since my Fedora will release will be
bumped to 27, but there won't be repositories for F27 on Copr ...
Unless this is handled somehow automatically by infrastructure during
Fedora branching, I don't like this proposal.
Vít
So the COPR plugin would merely need to have the
conditional removed and the COPR backend will need to have fake Fedora
26 targets that link to the current Rawhide ones.
