is there an arch Fork where I can compile every package myself?
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.
Fellow Arch user here (btw). It's exactly the same as building AUR packages. Clone a git repo containing a PKGBUILD, use makepkg to build it, and pacman to install it. The nice thing is you can host a repo of your built packages and install them on other systems really easily. The big downside is that dependency management is not automated, so it will take some time and annoyance to map out what packages you need to build and in what order, if you want a fully source-bootstrapped system.
