Yes, that sounds quite okay. Personally, I do per-package settings, but, well... I'm a software developer who develops software written in python, so I have a biiiit more patience than most people for juggling lots of python packages for multiple versions. :) Don't be me. :) > Just so I'm clear on where my live OS stands, this is the current > package.use setting. > > > */* PYTHON_TARGETS: -* python3_12 python3_13 > */* PYTHON_SINGLE_TARGET: -* python3_13 > > > This is the output of my normal emerge update with the above setting. > > > root@Gentoo-1 / # emerge -aukDN world > > These are the packages that would be merged, in order: > > Calculating dependencies... done! > Dependency resolution took 45.20 s (backtrack: 0/500). > > > Total: 0 packages, Size of downloads: 0 KiB > > !!!

There's no great guarantee since there's usually a very small tail end of packages which are very challenging to upgrade and take absolutely ages to migrate to newer python due to upstream developers not yet supporting it, and it needing "work", but whether those packages are important to any given person is very situation-dependent. Hopefully kicad is your only issue. That one is tracked by https://bugs.gentoo.org/952659 and using ACCEPT_KEYWORDS="**" will install kicad-9999.ebuild, which does support python 3.13. (Not saying you want to install totally unstable packages. But on the other hand, this does imply it's close to being ready. So... good news, right?) -- Eli Schwartz
