I just gave it a try, and woow!  :-)

It’s really nice to see that in action.

It lacks a couple of things such as the console server and client and
the pipe server, but tweaking this will be the funny part.  ;-)

Also, in GRUB, you currently load ext2fs.static and exec explicitly.
There’s now a /hurd/startup server that takes care of launching
/hurd/proc, /hurd/auth, and then passes control to /libexec/runsystem.
I suppose this is the preferred method, but hurd.texi doesn’t give the
exact GRUB commands.  Can anyone shed some light?

BTW, the image you posted is in “raw” format.  You would get a smaller
file by using the qcow2 format, which you can create with “qemu-img
create -f qcow2”.

Anyway, kudos, and keep up the good work!

Thank you,
Ludo’.
