I don't know if you can use it this way with systemd. Me and systemd
do not like each other and I will stay with openrc. Any of the sytemd
gurus has to see if this can be added/adapted to the systemd
'startscript'.
But anyway this approach will implicitly also wait till the network is
fully up as else no ping reply will be received. So the other wait
solutions are no longer needed.
You DO need to give your HD Homerun a static address on your router or
it might change over time!
