I do agree with you here, except that i'm trying to prevent this from
happening, because it's not something that can be easily fixed.
1. package A is backported into X
1b. package A-foo is backported into X-foo (subpackage)
2. package B is updated into Y at a later date
3. package update Y has a new dependency A-foo
4. person has X installed; but didn't install X-foo.
5. person updates B into Y
result is that Y pulls in as new dependency A-foo
but X conflicts with A-foo
so the update does not happen, and you get an ugly error.
my point is that:
1. since it's a new dependency, we can't know before we backport A that it
would be used as a new dependency for an update. because the update isn't
there yet, so we don't know beforehand.
2. more importantly, i don't see anyway to get this fixed without the user
manually fiddling with things (downgrading back to unbackported package;
or manually installing X-foo;)
Maybe i'm looking too far ahead, but unless i'm missing an obvious way to
cleanly fix this at the time of the update, this is still something we
