Plus, there may be patches in the src.rpm which are dist-specific. It may
or may not be possible [in rather ugly ways] to express the dist-requirements
in explicit and versioned R (or BR) by guessing maximum versions or by
introducing deps on specific versions. Broken explicit deps are particularly
bad, avoid them like the plague! We see them regularly in the broken deps
reports. Bad, bad, bad.
Further, the unmodified src.rpm may build fine for a newer dist, but
that's not the primary goal. The primary goal is to create and ship tested
and working binaries, prepared by the package maintainer(s), and which if
rebuilt without modification do not pretend that they have been made for
the different dist.
All I suggest is, don't limit packagers' freedom. When I know that %dist
expands to .fc4, I ought to be permitted to use .fc4 in my spec.
Anyway, this debate has found an end for me at this point. Keep fighting
for no visible benefit. Seeing a big thread about jpackage Release hacks,
I'm not going to voice my opinion on this any longer. %{?dist} is not
mandatory, and hence the work-around is to not use any dist tag at all
and to forbid anybody who modifies the spec to add %{?dist} without
prior permission.
