      Info:

      nixos-rebuild switch = build the new system configuration (from /etc/nixos/configuration.nix or flakes) and activate it immediately without reboot.

      • It builds the new system in /nix/store.
      • Updates the GRUB/systemd-boot entries.
      • Switches to the new configuration right away (systemd units, services, kernel params if possible, etc.).
      • Leaves the old generations available for rollback (nixos-rebuild switch --rollback).

      So: “switch” means build + activate now
