As other users mentioned, a new project called Artix has been created, that will try to create a base distribution based on Arch or Manjaro (depending on the repositories you use).
If I understood it, this will make arch-openrc and manjaro-openrc merge into this new Artix.
First of all, we do not have the resources nor the man power to maintain an openrc version of Antergos, so we will not.
Nevertheless, it seems that creating a “Community” edition based on Artix repositories and with an Openbox or LXQt DE wouldn’t be that difficult. We would be open to suggestions and collaborations.
I would also like to know if there are enough users willing to use an openrc systemd-free Openbox Antergos. It could be another DE, Artix is using LXQt (but don’t expect a Gnome openrc version).
Please, vote here!
Thanks to all of you
