I want to install the Systemd-free Artix Linux, but noticed on DistroWatch that it misses many packages. Being an Arch based distribution, is it possible to install packages directly from Arch repository? May the fact that the two use two different init systems (OpenRC vs Systemd) be a problem?
I am not familiar with Artix; however it says on their Wikipedia page:
Artix Linux has its own repos but most packages without systemd dependencies from Arch Linux repos and the Arch User Repository (AUR) can also be used.
For packages that do rely on systemd, they would need to provide replacement packages that can work with OpenRC (or whichever alternative init system you want to use). Note that this applies mostly to daemon packages, which run in the background and provide a service, which need to be started on boot by the init system.
Personally, I use Parabola, which is a libre distro that is also based on Arch. They support OpenRC and have a [nonsystemd] repository that contains replacement pacakages that work with OpenRC.
If it were me, I would post on the Artix forum, to see if they have something similar and verify if they have versions of the packages you want that work with OpenRC.
