I've no argument with --complete-graph working how it works as that's entirely logical. I was simply answering the question, why would someone use --oneshot for a leaf package? Ideally there's only one or two sets of trial install packages at any one time anyway, they were all installed at the same time either together or after having run a --pretend with them together so there were no known conflicts at that time, and they're taken care of one way or the other by the time of the next emerge -uDN @world (which is seldom >5 days, here, and more often I've reconciled within a couple days, unless one of the leaf packages is being stubborn and won't build for some reason, because a not fully reconciled, revdep-rebuilt and --depcleaned system /bothers/ me!) so it has no chance of messing them up because they're either part of it or unmerged. FWIW, FEATURES=buildpkg /does/ make life easier, too, because if there's a "trialware" leaf package that won't build, I can simply unmerge the dependencies temporarily, thus getting back to a fully reconciled system, and come back to it when I have more time to trace the bug down, or when there's movement on the bug if I'm depending on that. So yes there's reason to sometimes not have a dependency branch "covered" with an @world leaf, but there's no reason that should affect normal or even complete @world deps calculations, and indeed, I'm happy that it doesn't, as that would only throw in additional complications I don't want or need. But I'm wondering, is there possibly some method of doing the same complete-graph thing for the @installed set? I can't imagine ever using it or for that matter @installed in any form here as it just doesn't fit my admin style (as should be self-evident from the above), but since that's effectively what we're talking about... -- Duncan - List replies preferred.
