Painless NixOS Config

Auto-Upgrade

Configure daily auto-upgrades in upgrade-source.nix. Left as null, upgrades stay off; set to a flake URL, every host pulls from that flake once a day.

Example

Section titled “Example”

Say the configuration lives in a repository at git.example.com. Pointing the file at its flake turns daily upgrades on for every host:

upgrade-source.nix
"git+https://git.example.com/nixos-config"
