Wrong. Package masking is independent of keyword masking. Adding an atom to package.mask will mask all matching versions, no matter what their keywords. > So my understanding is that user needs to set something in: > /etc/portage/profile/package.provided showing an equal or higher > version number than what is available in portage (masked or not). > (To maintain users own package) package.provided is intended for use when you install something without portage - it's your way of telling portage the package is installed even though it's not in the database. > I ask because setting a higher version number might eventually need > bumping still higher... or if versioning changes somehow will `higher' > not be noticed. If an installed package requires a higher version than you have installed, then it needs it. Lying to portage about the version you have installed won't fix that, it just delays the breakage until later. Masking on the other had, produces a civilised error message telling you that package A needs package B greater than version N, and that it is masked. > Looking for a way not to have to check package.provided to make sure > versioning is still good. While package.provided does have some genuine uses, one of its main functions is to provide people who don't fully understand it with a simple way of producing hard to diagnose system breakages :( -- Neil Bothwick WinErr 010: Reserved for future mistakes by our developers
