Description

This command upgrades Lix to the latest stable version. This stable version is defined in the Lix manifest and updated manually. It may not always be the latest tagged release.

By default, it locates the directory containing the nix binary in the $PATH environment variable. If that directory is a Nix profile, it will upgrade the nix package in that profile to the latest stable binary release.

You cannot use this command to upgrade Nix in the system profile of a NixOS system (that is, if nix is found in /run/current-system).
