The standard thing is to place it in /etc/systemd/system. However,
this will not start it on next boot. For that you should "systemctl
enable nonstandard-network.service" (which will create a symlink in
multi-user.target.wants). To test it, you can do "systemctl start
nonstandard-network.service". To see get some info about what happened
do (as root) "systemctl status nonstandard-network.service". Notice
that anything your service prints to standard out or syslog ends up in
the journal, and the last bits of it is shown by systemctl status (for
more do "journalctl").
