GuixSD download options

[pothos]

Hello,

since the installation process is quite manual, takes long and ends in a
VM image for users who don't want to replace their current system, I
think there should be at least an option to download a tar file with the
content of a preconfigured root file system.
Then one could just extract it and run with systemd-nspawn -bD folder
(or if needed, use a new network device to support ssh if login with
machinectl is not enough).

Additonally a VM image would also be interesting.

Maybe this was already considered?

Regards,
Kai
