I tried following the documentation at:

  https://www.gnu.org/software/hurd/hurd/subhurd.html

But I could not get a subhurd to boot.

I tried:
- with the same image as the VM
- creating an image with debootstrap
- creating an image with crosshurd

I always get the message:

> /hurd/ext2fs.static --readonly "--multiboot-command-line=fastboot root=pseudo-root" --host-priv-port=1 --device-master-port=2 --kernel-task=3 --exec-server-task=4 -T device pseudo-root
> /lib/ld.so /hurd/exec
> /lib/ld.so: cannot open bootstrap file

or similar.

Any clue?
