Indeed.  Thanks.

    # mknod /dev/sr0 b 11 0
    # showtrans /dev/sr0
    /hurd/blkdev 11 0
    # settrans -cfgap /dev/sr0 /hurd/storeio sr0
    # showtrans /dev/sr0
    /hurd/blkdev 11 0

Apparently I have forgotten how to use settrans.  And I'm not the only
one; settrans usage has been discussed before again and again...  I
thought this would mean: *c*reate node if not there yet, *f*orce existing
translator to *g*o away, set *a*ctive and *p* translator.  Apparently I'm
wrong.

Yes, there is no Mach device called sr0 available at this moment.
