    Ok.

    Then we need to open the second discussion which is:

    Given a file handle 'X' how do I find out what ioctl groups I should apply to
    it. So we can go from

    if(MAJOR(st.st_rdev) == ST_MAJOR)
    issue_scsi_ioctls
    else if(MAJOR(st.st_rdev) == FTAPE_MAJOR)
    issue_ftape_ioctls
    else ..
    else
    error

    to

    /* Use scsi if possible [scsi, ide-scsi, usb-scsi, ...] */
    if(HAS_FEATURE_SET(fd, "scsi-tape"))
    ...
    else if(HAS_FEATURE_SET(fd, "floppy-tape"))
    ..
