safe-upgrade has always been like the proverbial dancing bear -- it's
a hack built on top of aptitude's resolver, and it's amazing that it
works at all, let alone as well as it does. One of the things that I'm
working on right now is building some ideas from safe-upgrade directly
into the resolver, and also implementing a few other overdue
optimizations that should accelerate the sorts of things safe-upgrade
does. (setting lots of manual constraints)
