Nixos need a replacement for nixos-rebuild!

idea.md

nixos executable

Basic features:

• installable as package, even on non-nixos
• is named nixos
• is written in C++ and binds to Nix C++ library (or maybe Haskell? Nodejs? What you think?)
• autocomplete, ncurses, Nix 2.0
• commit to Git by default on each rebuild

Subcommands

First I'll describe existing nixos-rebuild switches, that should go into new command:

• nixos-rebuild switch -> nixos rebuild, nixos rebuild --boot --activate
• nixos-rebuild boot -> nixos rebuild --no-activate
• nixos-rebuild test -> nixos rebuild --no-boot
• nixos-rebuild build -> nixos build
• nixos-rebuild dry-x -> nixos x --dry, nixos x --test
• nixos-rebuild --build-host -> nixos --build-on
• nixos-rebuild --target-host -> nixos --deploy-to
• nixos-rebuild switch --rollback -> nixos rollback opens a curses screen so you can select what to rollback to

Then, existing commands should be intergrated. All of those should work on non-NixOS:

• nixos-option X -> nixos option X
• show all options -> nixos options, the output should be compatible with FZF and fast
• nixos-generate-config -> nixos config --default, outputs to stdout
• nixos-install -> nixos install
• nixos-container XXX -> nixos container XXX
• nixos-version -> nixos -v, nixos --version. nixos -vv should be same as nix-info
• lustrate thing -> nixos lustrate --confirm-lustrate

And finally, some external projects should be merged in:

• nixos-infect -> nixos infect --confirm-infect, also nixos infect --confirm-infect --deploy-to

Anything missed?

Original nixos-rebuild commands are easier to type, though :)
