In order to be able to Further configure my system, I am looking for a fork of my current OS (artix with openRC as init system) in which i am able to compile every package from source in order to Further configure it with make flags. I am currently not using gentoo, and because the packages in its default repos are only updated when necessary, and the break-my-gentoo repo is more of a joke than an actual replacement for arch. However, if someone can recommand me a repo with similar package updates as arch, I would be looking at installing gentoo.
EDIT: Thank you for Pointing out to me that Gentoo can have newer Packages too. I did indeed not know this, and therefore just stamped off Gentoo as a stable rolling release distro. I will be looking at learning more about gentoo and eventually installing it, once I know how to use portage.
You could try Guix! It’s ostensibly source based but you can use precompiled binaries as well (using the substitute system)
It’s a source-first Functional package distro like Nix but uses Scheme to define everything from the packages to the way the init system (Shepherd) works.
It’s very different from other distros but between being functional, source-first, and having shepherd, I personally love it
