You can take any system configuration file and build a shared or free-standing
vm with the "guix system" function. It's really easy this way.
"guix system vm config.scm" would produce a vm and in the end you get a
shell script you can use to start this vm.

Wouldn't simply keeping the configuration file(s) in a git help
(for a start)? This is what I do personally:

For infotropique I have this combination of plain config files (templates)
and (almost) the same content in variations of the before referenced "install.scm".
