How to mount USB pen drive (Debian/GNU Hurd amd64)

Hi,

So I've successfully dd-ed the 2025-11 Netinst ISO (for amd64)  to an USB =
pen drive and booted from it=2E The installer complains about not finding t=
he CDROM=2E=20
I thought that I could mount the pen drive under /media/cdrom, but I don't=
 seem to be able to do it=2E
Things I've tried:
* mount -t iso9660 /dev/{sd0,ud0} /media/cdrom
* settrans -c /media/cdrom -a  /hurd/iso9660fs /dev/sd0
* Also: settrans -a /hurd/rumpusbdisk /dev/sd0 , but then realized it's pr=
obably setup diring boot

Any pointers will be greatly appreciated=2E

Thanks,

Alexander
