[Nix-dev] NixOS on a machine with only one user

[Amy de Buitléir]

NixOS noob here. I'm using NixOS on a machine with only one user (me).
What's the best strategy for installing packages?

Installing into the global system environment
- or -
Installing into a normal user profile 

It seems that the second method would be a bit more convenient, especially
if I add and remove new software frequently. Which I do.
