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.
