I am arch user by now. Tried nix package manager on it and learning nix thee days. I was thinking of switching to nix as I was not able to replicate that much Declarativeness on my setup. But barrier is almost Everything Nix is on Github,Something which somehow belong to Microsoft and is not good for privacy.
So can Nix community host a Gitlab or forgejo or Something else as an alternative or maybe permanently move it (so that I can switch to nix)?
I dont really have enlightenment for you unfortunately.
As someone else pointed out, in terms of fork i think what there is out there currently is lix as an alternative to cppNix, and i think auxolotl is planning on replacing nixpkgs/nixos
