 |
|
Hi all,
Is it possible to unemerge a package and its dependancies that installed with it? Currently, when a package is installed because it was a dependancy, it isnt removed when the package that depended on it is unemerged.
This is offcourse a good thing because other packages can depend on it too. But if this isnt the case there is a good deal of bytes just sitting on your HD doing absolutely nothing..
Can the current version of Portage/Emerge deal with this? Or maybe Portage2.. |

Good question -- I haven't heard of that feature being added, but it certainly would be welcome. It's a pretty tough nut to crack, though -- coming up with a system-wide dependency matrix is no easy feat of programming. Debian doesn't do this very well (though cruft is making some good progress) and I'm not aware of other distros that do this any better.

It's late and I need some sleep, but if you have a list of the manually installed files, you can calculate all needed dependencies (just like emerge already does, think of rebuilding all package, but only add the dependencies in a temp list.) (it will take some time... but well don't need to do it for every removal, just make a seperate option), put them in a list, compare this list with the installed packages, and you get the packages that aren't used by the system. So all manually installed packages are kept and dependencies are recalculated and checked againt the system,
Well I probably forgot something,.....sleep........ Cya, lX.

This is getting into the feature request stage, so I'm going to move this over to Gentoo Suggestions.
