Oh, this was discussed so many times already... There is NO single correct solution to such problems. And some mathematically correct solutions are impractical (e.g. half of the tree rebuild), so other ones which are good enough are preferred. As long as imperfect solution works fine, I'm ok with it. As for paludis, I tried it. Everything mentioned below is my _personal_ experience and not supposed to pretend to be objective. So, from my experience paludis turned out to be: - slower then portage (I don't care here if it is more correct or not, I just want to do my daily job); - not fully compatible with portage: it triggers a lot of problems portage doesn't. While this may be good for QA and tree improvement, I don't want to hang my workflow due to these issues; - importare instead of local overlay is a complete nightmare: usually I don't want to install package exactly as make install does: often it lacks some required files (e.g. init scripts) or installs something unneeded on Gentoo system. Besides I use local overlay to test packages before committing to public overlays or Gentoo main tree. Lack of local overlay support is sufficient to send paludis straight to waste bin on my systems. - completely insane command line options, arguments required to do what I want to do are quite cumbersome, portage is much saner here. Everything above is just my personal experience, so your mileage may vary. But after all that issues I don't even want to try paludis in the foreseeable future. Best regards, Andrew Savchenko
