># Modifies NetworkManager-wait-online.service to replaces the call of
># nm-online by waiting for all the wanted routes to be up and that the default
># gateway (if any) is reachable.
>
># Uses ip and arping.
>
># To install for example as:
>#
>#  /etc/systemd/system/NetworkManager-wait-online.service.d/routes-gw.conf
>#
># Then adjust the ROUTES MAXWAIT variables below.
>
># Example for the ROUTES:
># 
>#  ROUTES=" \
>#    default \
>#    1.2.3.0/24 \
>#    4.5.6.0/24 \
># "; \
