And --clean cleans a package, that means when you have two versions of a non slotted ebuild installed. It automatically happens after you upgrade a package, first the new version is installed parallel to the existing one, then the old one is "cleaned out". You should never need a manual --clean :) But it should never break anything, which --unmerge can. Regards, Sascha
