# Started (never enabled) by pxe-nic-carrier, the networkd-dispatcher
# hook, when the imaging NIC gets carrier back. Re-checks the imaging NIC
# before dnsmasq serves again: if dnsmasq was running (or the hook stopped
# it on carrier loss), "systemctl restart dnsmasq" so its ExecStartPre
# guard decides; otherwise it only refreshes /run/pxe-nic-status.json.
# The hook restarts this unit on every carrier gain and stops it on a
# carrier loss, so the newest event wins.
