Hi!

I've found an issue that appeared after the change in -Sc behaviour. It now removes "uninstalled" packages from cache which is good for majority of users, but is bad for shared pacman cache users. With a pacman cache shared between machines it is impossible to correctly clean it with pacman if a set of installed packages on them is different. I remember there was at least one script posted here or on forums that removes old version of packages from a specified directory (it was provided as a helpful tool for managing local repositories AFAIR), but I cannot find it. Could someone who have this (or similar) script please share it? It needs to be posted to our wiki page about a shared cache, and maybe Phil's rucksack script needs to be modified as well.

This one http://archlinux.org/pipermail/pacman-dev/2007-March/007767.html maybe?

I grabbed this one some time a while back, it is probably the same as one of the above. I can't remember if I made any modifications of my own to it. -Dan

Ahah, that's funny. When pacman removed the old versions from the cache, people wanted to remove the no longer installed versions. And now that pacman removes the no longer installed versions, people want to remove the old versions from the cache. But there is indeed a problem here. For a not shared cache, the new behavior makes more sense. But for a shared cache, the old behavior was better. So in that thread, all the first scripts should emulate the new 3.1 behavior (and so should be unneeded now), but maybe the last script there from Spider emulates the old 3.0 behavior? In any cases, it doesn't seem possible to satisfy everyone. So it might be better to use external scripts for that indeed..
