+1 to defining what's inappropriate for Conflicts and how to work around
+1 for commenting anytime Conflicts is used.
-1 to ask the Steering Committee to audit these on a case by case basis.
Conflicts should be infrequently used, but it's not really something
that I think needs to be evaluated like that. It's not political and
it's not really an abuse of a tag when used correctly. It's a technical
decision and should be worked out by a reviewer and packager. (And
"after importation QA" if we had that.)
Maybe making it clearer when it's okay to use Conflicts would be a good
idea if we do that though:
The only time Conflicts are allowed is when a package does not Require
the other package but can make use of it as long as the other package is
of the correct version. When this occurs you are allowed to use a
versioned Conflicts to specify this and you must also include a comment
which explains the reasoning:
# When ypbind is older than 1.6-12, the initscripts explode horribly.
# ypbind is not required for initscripts to function.
Conflicts: ypbind < 1.6-12
If there is another instance where you think a Conflicts is required,
please ask for input from the Packaging Committee so they can discuss it
and decide if a change is needed to these Guidelines.
