it is a starting point, however the disk image (or clones) are:
- created using kick-start
- booted as base to install packages
- booted as build to build libvirt
- booted as east, ..., to test
so a simple oneshot would have happened long ago

the .network files - all of which are installed - now look like this:
https://github.com/libreswan/libreswan/commit/c89711225f3a1c4384d6df8d17b2508997e26a0e
so the network is figured out using systemd
