We need to decide upon a solution to the -flags problem. The proposed solutions are: 1) Disallow all negatives. Disadvantages: we don't tend to disallow things just because users could shoot themselves in the foot with them. 2) Allow negatives, and document how to use them correctly. Disadvantages: sooner or later, some developer isn't going to read the docs, and will really really screw things up with a misunderstanding. 3) Reorder USE flags. Disadvantages: can't disable flags set by a group. Breaks existing USE lines. 4) Have portage warn on dodgy USE flag lines. Disadvantages: tricky, hard for the end user to figure out. 5) Use some weird tristate notation. Disadvantages: not everyone has the slightest clue what set theory is. I'm in favour of 2) personally, but others disagree. I'd like a proper discussion on this before trying to get the GLEP through. -- Ciaran McCreesh : Gentoo Developer (Vim, Fluxbox, shell tools) Mail : ciaranm at gentoo.org Web : http://dev.gentoo.org/~ciaranm
