No sorry, Fedora Atomic has allowed changes to /etc
since at least 2019. Regarding NixOS, the consensus is that it’s an immutable distro. The immutability of /nix/store/
suffices for this.
Your notion on Fedora Atomic was false. So, what other ‘immutable’ distro did you have in mind when making that comment?
Please stop harassing me. And idk. I saw that issue but at this point I think it was just misinformation.
