21:41 < Betelgeuse> zmedico: ping
21:41 < zmedico> Betelgeuse: pong
21:42 < Betelgeuse> zmedico: What do you think about a package.keywords atom that would automatically unmask the needed stuff.
21:42 < Betelgeuse> I wast thinking it would go like this:
21:42 < Betelgeuse> 1. try stable
21:42 < Betelgeuse> 2. try latest ~arch
21:42 < Betelgeuse> then for installed stuff only update if the ebuild is gone
21:42 < Betelgeuse> and then only the oldest ~arch
21:43 < astinus> Betelgeuse: the oldest ~arch could be older than stable.
21:43 < Betelgeuse> astinus: then use stable
21:51 < astinus> Betelgeuse: sounds like a neat idea, but I'd be worried about the "oldest arch" bit. If you're auto-unmasking, the *oldest* arch may be an issue, ie: if you have app-foo/foobar-1.0.1-r1 as the *oldest* and 1.0.1-r7 as
                 teh newest, chances are there are fixes in there you'd want
21:51 < zmedico> Betelgeuse: I suppose that sort of thing could be represented as a package set. It's a bit simpler if the set can just accept keywords on all deep dependencies.
21:52 < Betelgeuse> zmedico: Yeah sets would help
21:52 < Betelgeuse> zmedico: I was unmasking xorg-server-1.5 earlier today
21:53 < zmedico> seems like it will require backtracking to implement
21:55 < zmedico> or maybe just a lookahead mechanism would work
21:56 < zmedico> I guess you'd sort of build a mini graph to determine the set
21:56 < zmedico> prior to building the whole graph
21:57 < zmedico> it's similar to how PROPERTIES=set would be implemented
22:01 < zmedico> seems like fun
22:03 < Betelgeuse> zmedico: Even the ability of people to list pkgs to file and then apply keywords to all of them would help
22:03 < Betelgeuse> zmedico: when set files come with the tree
22:03 < Betelgeuse> zmedico: I guess Portage only misses the latter part
22:04 < zmedico> yeah, that's a lot simpler to implement
22:04 < Betelgeuse> could just start with that and then go further
22:04 < zmedico> good idea
