I’m running ~x86 Gentoo here, eix-sync && emerge -Dav world every few days till something strange started happening. Portage wanted to reinstall everything, I mean, hundreds of packages to the same version as before, no new use, no new anything, just reinstall all packages for the pleasure of compiling and heating up my Macbook pro 🙂
Well, now I figured out that adding the “-u” flag to emerge restored the expected behaviour.
Maybe I was supposed to use “-u” since day one but the fact is I didn’t, and emerge worked fine until now. Anyway, if any of you face the same issue, try “-u”.
