[bug#41785] [PATCH] DRAFT services: Add 'hurd-in-vm service-type'.

[Mathieu Othacehe]

Hello Jan,

> TODO: Figure-out how to run this hurd VM inside a VM.

Just to clarify things here, we now have the "disk-image" command that
produces a Hurd bootable disk-image. The "vm-image" command is almost
working, and should produce a very similar result.

The "vm" command that produces a vm-image and spawns a VM isn't working
yet with the Hurd. This command is for now passing directly "kernel" and
"initrd" arguments to QEMU, so a few adaptations will be needed.

Now the goad of hurd-in-vm-service-type is to provide a service that
does almost the same thing as the "vm" command, but as a service, right?

So, I don't get why would we need to run a Hurd VM inside a VM. I've
been struggling a lot with running nested layers of virtualization (for
system generation before the recent patches), and the result is often
too slow to be really usable.

Thanks,

Mathieu
