Ramdisk is not a kernel feature in the Hurd.  It is entirely implement in
user space.

You can use the "copy" store on top of a "zero" store to get a memory-backed
file with a fixed size.  Try

$ settrans -ac myramdisk /hurd/storeio copy:zero:16M

for a 6mb "ram disk" in myramdisk.  There should now be an empty file with
16 MB, but it doesn't occupy any disk space, it is backed by ram (and if the
translator dies, the data will be lost).

An alternative is the tmpfs, but it is defunctional right now, I think.

Thanks,
Marcus
