I don't think I have seen something like this before; but from the sound
of it, I'd say something went wrong with the mkfs? Perhaps something
wrong with the loopback setup? I'm not convinced this is really a Hurd
Looks like mkfs promised more than the partition could actually contain.
How did you run it?

I created it using this:

     qemu-img create -f raw hurd.img 1GB
     losetup /dev/loop0 hurd.img
     fdisk /dev/loop0  (create one partition)
     losetup -d /dev/loop0
     losetup -o 32256 /dev/loop0 hurd.img
     mkfs.ext2 -b 4096 -I 128 -o hurd -F /dev/loop0

To make it simple, I'd advise running mkfs again, giving it 261048
(i.e. 1069254144/4096) as number of blocs.

Good idea.  I will try that later.  At the moment I am just using the
Debian Hurd image and deleting all the files...
