@iska@mstdn.starnix.network You can add custom repos for binaries, there is an official repo for non-free stuff. The sources are like this: https://github.com/void-linux/void-packages
It's just a git repo with all the scripts and templates in srcpkgs (smth like ebuilds in Gentoo). I use Void on PPC and PPC64 musl machines which are no longer officially supported so I use it mostly for fixing stuff that breaks, but of course you can add your custom stuff, commit, pull the changes from upstream and rebase your custom stuff — easy as that!
