Re: [gentoo-dev] RFC: Should preserve-libs be enabled by default?
Marius Mauch a écrit : So, do you think it should be enabled by default? Does portage have a way to report which libraries it is keeping around because of preserve-libs ? If there's an easy way to figure that out, then enabling it by default is a very sane and sound idea. Cheers, Rémi -- gentoo-dev@lists.gentoo.org mailing list

Is there a way to have portage delete the libraries once it's sure they're no longer necessary? If so, is that done by rebuilding the owning package itself, or by editing the owning pacakge's contents and removing the old library? Does @preserved-rebuild contain just the affected packages, or the package containing the old library as well? (i.e. Does an emerge @preserved-rebuild ensure that the old library will no longer exist on your system, or not?) Basically, if I can safely replace revdep-rebuild with emerge @preserved-rebuild then I'd be happy to keep it enabled. If it's going to leave cruft on the system (or then require manual rebuilds of packages containing preserved libraries to clear out the cruft) then I'd personally be inclined to turn it off and stick with revdep-rebuild...

I can't rule this out completely but thinks it's very unlikely, as preserved libraries are specially tracked and the user is notified about their existance after every emerge operation (similar to glep42 news). Part of this should be addressable by keeping track of the version that installed them and checking it against the distributed GLSAs... Thanks, Donnie -- gentoo-dev@lists.gentoo.org mailing list
