Is there a distro with:
- Immutable root
- Active work (examples) toward reproducible packages
- A smaller learning curve than NixOS?
Is there a distro with:
NixOS learning curve maybe is not so hard. You can start with default configurations and installed Calamares what is as simple as on other distros. Than look for options and try.
Otherwise, Flatpaks are reproducible (build with flatpak-builder as on Flathub).
I just installed NixOS on an old laptop. It's really easy to start but the documentation sucks and there aren't many great tutorials.
