# Pull-based NixOS updates for hosts that can't be pushed to reliably.
# CI builds the system closure on muffin (which Harmonia serves), then
# records the output store path at /deploy/<hostname>. On boot this
# service fetches that path, pulls the closure from the binary cache,
# sets it as the boot profile, and reboots into it.
#
# Runs before the display manager so the user sees progress on the
# console instead of staring at a frozen Steam loading screen.
