I'm glad to hear that. In fact, this prompt me to express a more general
"platform requirement" for all this discussion. It would be a worthwhile
goal, once an interface with APT and friends is set up, to define a
common way for package shipping dependency solvers to register
themselves as alternative solvers. Ideally, the sysadm might want to
change the solver used by APT by simply specifying a configuration
option, possibly on the command line.

I understand I'm jumping the gun a bit with that, but it's something we
should keep in mind as a goal. Maintainers of (several!, hint hint)
solver packages might in fact already advance proposals on how to
declare / register solvers.

Cheers.
