We should document what Portage does; but from the word 'backtrack' I think it tries with what it is given, and if it doesn't succeed it goes one step back and tries to do it with more. But how exactly that is implemented, I think only people like Zac and Arfrever can tell us; or we read through the relevant code ourselves. -- 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
