It sounds crazy to use gentoo-x86 without a cache; to some extent, the earlier mentions on this ML by Ciaran that we should improve input would make more sense if would want to run without a cache. But I feel like this shouldn't be a topic of discussion unless we intent 'works fast on a plain CV checkout' to be an actual feature. I haven't checked, but doesn't Portage in that case build its own cache? > It is helpful for users cause it can automatically find solutions for > users that are otherwise unsolvable (and thus avoids the user having > to find a solution to the depgraph manually.) If we document how to process --depgraph=0 output, I believe it could just as well be used; but yes, it basically involves having to run a few manual upgrades (emerge -1 ...) and/or masks to get going. But you can do those things in seconds rather than to wait a few minutes... Some of these Portage could even do automatically regradless, like for instance the 'no parents' slot conflicts; in which case I think you can just always upgrade to the newer version, instead of outputting them it put them as upgrades at the end of the emerge list I think. But I haven't investigated that further, I'm just getting tired of seeing 'em. -- With kind regards, Tom Wijsman (TomWij) Gentoo Developer E-mail address : TomWij@gentoo.org GPG Public Key : 6D34E57D GPG Fingerprint : C165 AF18 AB4C 400B C3D2 ABF0 95B2 1FCD 6D34 E57D
