I see no logical connection between the two. equery uses --force-masked shows it, and many more. I promise you, far far far more than once per year does a package.use.force get added to some package in the tree. >> The default change is more >> convenient for various reasons, and has little value in removing.

I empathize greatly. As a former user of a binary distro I would not be a Gentoo user at all, let alone a Developer, if Gentoo didn't have binary packages. It was *the* reason I switched, and quickly became a Developer. For a computer that old, I think you would benefit a lot from optional binary support: https://www.gentoo.org/news/2023/12/29/Gentoo-binary.html It supports USE flags perfectly -- only installing binaries that match your USE, automatically building from source otherwise. You can do it per package, even: emerge --sync emerge -puDU @world # packages which are a big burden to compile, listed in -puDU @world emerge -1auU --getbinpkg llvm-core/llvm gcc <...> emerge -auDU @world -- Eli Schwartz
