nix-installer not correctly detecting openSUSE MicroOS as an immutable system (where using /nix directly fails)

I tried to install Nix using the nix-installer on a openSUSE MicroOS system. This is an immutable distro similar to Fedory Silverblue/Kinoite/..., but it does not use rpm-ostree.

The installer did not properly detect that it would not be able to write to /nix/ directly and failed due to that.

Running the installer with nix-installer install ostree --persistence=/opt/nix worked successfully.

If desired, I can paste the /etc/os-release from the MicroOS system tomorrow.

I'm glad the ostree variant worked for you! I'd love to see that /etc/os-release.
