Indeed, mine too.

Well -- yes. That was my thinking.
We would not normally use such a VM-in-VM thing; when you want a Hurd VM
using the "vm" command would be great (or as now, create a disk image
and start QEMU).
However, for writing and debugging (testing?) this Hurd-in-VM service, I
thought adding it to a linux bare-bones.tmpl and using guix vm on that
was a nice and "trivial" way to test it. That proved so troublesome
that I added it to my system.
As I understand it the intended use for this service is to have a real
simple way to add a Hurd VM to some build machines, so that we can
easily create a herd of Hurd-VMs to aid the Hurd work. Ludo?
Greetings,
Janneke
