Sorry, didn't mention anything at the time because Niels reply seemed like a better answer to this problem, that was already supported. In any case, while this might be nice to have, it requires pretty much reimplementing parts of dpkg-architecture in C to be usable from libdpkg or dpkg itself, because we'd need to map the .deb arch into the multiarch triplet, which we should not be hardcoding internally. This has crossed my mind doing, and I think I started work in that direction, but it has also not seemed a very urgent thing to do TBH. Thanks, Guillem
