# wg-quick's background route monitor (spawned by `wg-quick up wg0` to
# react to WAN interface/address changes) isn't rc.d-managed, so there's
# no `service ... status` for it. If it dies, wg0 itself stays up - the
# kernel interface doesn't depend on it - but the box stops reacting to
# WAN IP changes (e.g. a DHCP lease renewal) until wg-quick is restarted.
