Yick. Consider the following use case (picking Vim because I know the package and can think of an easy, clear example): Fred builds a repository containing some Vim plugins that aren't in the main tree. Fred lets other people use this repository. Then, Fred tries to make an ebuild that needs Vim built with tclinterp enabled. Problem! The Gentoo ebuilds don't turn on (even via USE) tclinterp. So, Fred creates his own Vim ebuilds that do support tclinterp. Now he needs some way to DEPEND upon "my Vim ebuilds, not the Gentoo ones". Now consider the following use case for why "if a package is already installed, try to restrict future installs to packages from that repository" is less than ideal: A collection of bleeding edge users creates a repository containing updated ebuilds for unstable Gnome 2.30_alpha releases. Various people use this repository. Then, the official Gentoo ebuilds for Gnome 2.30 stable are released, and the bleeding edge users don't update their repository. Users who were previously using the 2.30_alpha ebuilds will be stuck with them. So, default behaviour should be "pick from any repository", but it should be as easy as reasonably possible for both ebuilds and users to specify a repository restriction where necessary or desired. -- Ciaran McCreesh : Gentoo Developer (I can kill you with my brain) Mail : ciaranm at gentoo.org Web : http://dev.gentoo.org/~ciaranm
