it is time. :)

I was trying to set this up and am now stuck at the point where I want QEMU to
offer a directory from outside QEMU (Linux) to the system running inside QEMU
(Hurd). With a Linux guest, I would use this inside QEMU:

    mount -t 9p -o trans=virtio,access=any,msize=128k mmdebstrap /mnt

But when I run this with hurd, I get:

    mount: mmdebstrap: filesystem type `9p' unknown

I run QEMU with this option:

    -virtfs local,id=mmdebstrap,path="$(pwd)/shared",security_model=none,mount_tag=mmdebstrap

Does the plan9 filesystem work or is there a better way to achieve the same
thing with Hurd as the guest?

Thanks!

cheers, josch
