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.
Most AUR packages that aren’t postfixed with “-bin” are compiled on your system. Most distro packages have AUR counterparts, but they’re usually git builds, so using them for every package you can will probably just break your system.
Also, the Arch repos are pretty much just an “AUR with binaries” - they contain the same PKGBUILD files used by AUR packages, because that’s how Arch packages are built. So you can just download an Arch package PKGBUILD, modify it however you wish, and then build and install it.
