When Koji looks for a package, it does a depth-first search.
(f21-build, f21, f20, f21-released is the order in your case) The
priority influences the ordering.
Hmm.. I think I would want that order to be f21-build, f21-released, f21, f20 instead. So
I assume I need to change the priority somewhere.
They're just arbitrary numbers. I
usually use multiples of 10 to start, so that if I ever need to inject
a tag, I can pick a priority in between the tags that are already there.
The numbers you see in list-tag-inheritance in the parentheses are tag
IDs, not priority, in case that is confusing you.
That makes sense, but I still don't know how to *see* the priority values (short of
diving into the DB, which I hope is unnecessary). The "koji
list-external-repos" command shows priorities for those, but the only mention of
priorities I see with tags and/or inheritance is via "--priority=N".
