Another way is if there's a > fatal error during certain parts of the upgrade process. 1) If a package only ever had one slot, it cannot ever have two versions installed at the same time. That guarantee (of only ever one slot) can be given for the portage tree (sic). Obviously it doesn't work for overlays, but there are many things we don't care about for overlays. [A] 2) If a package manager leaves two versions of a non-slotted package "installed" somehow, that package manager is fundamentally broken and its author should forever refrain from specifying anything. It's not our job to work around Paludis failure modes. [B] [A] Let's say there are overlays which package StarOffice, Go-OOO and some other random OOO fork. Do I have to block them all because of file collisions then? [B] The package manager could be broken to leave some random files on the system too... maybe we need some more blockers or specific error handling in all ebuilds? - -- Andreas K.
