NixOS:
- Largest and most up to date package repository (no need for flatpack/appimage/snap ect)
- Reproducible
- Declarative
- Rollbacks you can select at boot time
- No dependency conflicts
I think it will easily be the number 1 distro if/when they can :
- the steep learning curve (e.g. have a gui installer EDIT: As in a GUI software centre)
- documentation
- have more tools use nixos and have nixos in mind (e.g. there are a couple of tools that didn't work for me because of specific C libraries not beeing present/configured on nixos that are present on other distros. some libraries implicitly expect these to be present).
yep, I mean a GUI based software centre
