That (debootstrap + reusing existing GRUB from the i686 installation)
is what I was doing, yes, in one of the two setups that I've tried. On
the other (on a different host) I was doing grub2-install myself. In
both cases I got the same result, with GRUB working fine, but then
rumpdisk apparently misbehaving.

I could reproduce this if we want to debug it further, but Samuel's
image works great for now.

Yes, I'd like to use libvirt eventually too, like I'm doing for my
i686 Hurd VM. But I need greater control over how I invoke QEMU for


P.S. I have posted all of my patches, so if you're interested in
hacking on aarch64-gnu Mach, you should be able to build the full
toolchain now.
