:= only makes sense when something is both a DEPEND and an RDEPEND.
Actual behaviour, for Paludis, is that it rewrites := deps to :=blah
when writing to VDB any time it can, and leaves anything it can't
as := deps. Verifying sanity of := use is left to developers and
the QA tool.
... and the spec.
The spec's well defined. It just tells you how := works, not how to use
it in a sensible manner. Pretty much the same as for everything else.
Sorry, but I disagree.
The only sensible thing you can do with multiple matches on := slots
(and ||=, if that route is taken) is to take the slot of the best
matching installed version, and require that ebuilds do that too. In
real world cases, this works just fine.
so, ebuilds should use best_version instead of has_version for
example. That's what I meant and what I miss in the kdebuild-1
spec :-)
Generally, it just works, because packages are usually fairly good at
picking up the best installed version themselves anyway. But yes, if
you have to pass a version manually to a package, best_version is the
way to do it.
And what about a function to tell the PM explicitly which slot of a
dependency has been used (as an alternative)? Or should that decision
always be left to the PM? (that's something I'd expect to be in the PMS)
