User Environment: Difference between revisions

Profiles and '''''User Environments''''' are Nix’s mechanism for implementing the ability to allow different users to have different configurations, and to do atomic upgrades and rollbacks. There may be many user environments: different users can have different environments, and individual users can switch between different environments. In Nix — and thus, NixOS — a '''''User Environment''''' is a core concept in understanding how the system operates.  

As such, it is covered in pieces in many parts of the {{Nix Manual}}. This page serves as a quick reference. Note, user environments are not currently covered at all in the {{NixOS Manual}}. User environments are mentioned in the {{Nixpkgs Manual|name=Nixpkgs Manual: Chapter - Python Install Guide|anchor=#python}}; there, a brief summary interspersed with Python install instructions.
