I believe I know the answer to the question... the real question is, how can I work around it? ;)
I am running the development branch of www-client/chromium (currently 8.0.552.0). As a result, I like the latest builds to always be unmasked when they are available. However, once in a while there is a bad apple in the bunch and I'd like to mask that atom specifically. 8.0.552.0 is one of those that I would like masked. What I'd like to do is: /etc/portage/package.unmask: www-client/chromium /etc/portage/package.mask: =www-client/chromium-8.0.552.0 This case shows that, in fact, the mask comes first, as the atom in question is definitely unmasked in that scenario. I have tried putting either line into /etc/portage/profile/package.mask or .unmask, to no effect. I know I could do this by putting noninclusive comparative statements in .unmask, ala: <www-client/chromium-8.0.552.0 >www-client/chromium-8.0.552.0 But this seems somewhat clumsy to me. Does anyone know a trick to do what I'm looking for? Thanks, -Andy
