Pkgcore is an alternative to portage, it is precise, fast and capable however it isn't usable because it lacks to main criterian as far as I know. 1. pmerge cannot work with --jobs 2. pmerge cannot detect newly set useflags in installed packages with --update however if those and possibly a few minor other issues are ironed out, then portage will be blazing fast, of course only if it adopts pkgcore. To my understanding current portage is not well documented and none the less very slow. The solution pkgcore brings to the table is nothing which should be overlooked, it is truly a wonderful solution to portages gripes. Pkgcore: https://github.com/pkgcore/pkgcore Please give it serious consideration. pmerge -uD @world is blazing fast in comparison to gentoos default.
Here are some more pkgcore dependency resolver feature requests: * backtracking (see emerge --backtrack option) * automatic slot operator rebuilds * equivalent to emerge --autounmask and --autounmask-continue options * soname dependencies
