It seems like you're trying to bypass an important function of repoman
though. The idea is that repoman is supposed to protect users from
experiencing unsatisfiable dependencies of this sort, and use.mask
accomplishes that. With your use.unsatisfiable patch, it makes repoman
quiet, while leaving users unprotected from unsatisfied dependencies.
