dselect is executing the mount command, which is a full native mount
on GNU/Linux. The GNU system, though, has a mount script that makes
use of the real thing (Hurd translators). That script seems not be
fully compliant with GNU/Linux mount.

Dselect should use settrans and friends directly when the __GNU__
macro is defined, and mount otherwise (for both GNU/Linux and GNU/*BSD).

you said wanted to learn about the Hurd. could you fix that problem?
It shouldn't be hard (check settrans --help). I think it'd be like this:

mount -t iso9660 /dev/foo /cdrom --> settrans -af /cdrom /hurd/isofs /dev/foo
umount /cdrom --> settrans -f /cdrom

See http://www.vmlinux.org/twiki/bin/view/Hurd/BtsFiling for patch
sending instructions. (and don't file this as important or you'll be flamed ;)

cheers,
