sudo nixos-rebuild switch resets the machine

[douglaz]

If we run sudo nixos-rebuild switch it will uninstall everything and remove all the user access, making the machine unavailable. We should have some kind of protection against this

By default sudo nixos-rebuild switch will set the machine to use /etc/nixos/configuration.nix configuration.

Normally npcnix will do something like sudo nixos-rebuild switch --flake . in a directory that contains a flake with the desired configuration.

If you were to run sudo nixos-rebuild switch --flake . with the desired config again, everything would switch back to how it should be.

But yeah, I have not thought anyone would be running these manually. :D

I think if we delete /etc/nixos/configuration.nix, sudo nixos-rebuild switch will just fail.

Oh. And I think setting install = true in the terraform again would restore the machine as well.
