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
