Oops, yes I missed that. New try:

No, it's not a cdimage (the name of the url is fu), this is a
pre-installed qemu qcow image. The README says
To give Debian GNU/Hurd a try, it is probably easier to simply run the
preinstalled image, which is provided here: [...]
so using this instead of installing something myself ensures we are
looking an the same thing. Is there any newer image that I could try?

Yeah, so what I've tried should really work, right?

Ah, that makes sense, right.

Hmm, the image above already has wd0 (part:2:device:wd0)...but it does
not use rump, now it really gets confusing...
