Agreed. Still, in my experience, problems that are not seen on
amd64 are the vast majority of timesinks. Usually, by the time
non-amd64 shows up on a non-security bug, the Basic Bullshit™ has
been sorted. And even if it isn't: Arches are usually quick to
point it out and the rest of arches move on to the next bug. The
truly arch-dependent bugs are what wastes my time:
For example:
- dependencies not being keyworded for arch or ~arch but only
amd64/~amd64
- dependencies not even building on ~arch, but on ~amd64
- package assuming availability of gcc/ghc/Python-X.Y when
arch/~arch only has something for <Y or <X
- my favourite: assuming udev is at version X for arch/~arch when
it has been broken there for roughly twelve kernel versions due
to udev/systemd upstream not caring. The information is one
equery-y command line away, but no, let's file that bug.
Having every arch team chase the deps for every package is very,
very frustrating, since it is so trivial a problem. We need a
tool that answers the question: "I want to mov cat/pkg-1.2.3 to
stable for arches a, b and c, what do I need?" for _every
package_. Some groups seem to have tooling for this, but it is
far from easily (obviously?) available, so every team gets to
re-discover dependency hell. Ruby is especially bad since
FEATURES=test make the depgraph explode (and sometimes circular).

Tobias
