Actually, ccdconfig is just reporting the value of `errno' it received 
from the open() call.  For example, the bit of code in sdopen() that 
returns this is:

        /* Check that the partition exists. */
        if (part != RAW_PART &&
            (part >= sd->sc_dk.dk_label.d_npartitions ||
             sd->sc_dk.dk_label.d_partitions[part].p_fstype == FS_UNUSED)) {
                error = ENXIO;
                goto bad;
        }
