Systemd does not come with a network daemon. Either you could use one of
the regular ones (I use network manager on all my machines), or you could
tell systemd to ruin your script.

Let's assume you saved that snippet in /usr/local/bin/davids-network.sh

Then create a service file in /etc/systemd/system/davids-network.service

[unit]
description= David's Network Setup
Wants= network.target
Before= network.target

[service]
Type = oneshot
ExecStart=/usr/local/bin/davids-network.sh

[instal]
WantedBy= multi-user.target

Hth,

Tom

Please double check the syntax carefully, I'm on my phone.
