sigh ... surely i never typed "rm /dev/sdb" but nonetheless
it disappeared.  i recreated it and tried wipefs.  my various
commands are in the b1 file shown here:

# bin/b1
# sudo mknod -m660 /dev/sdb b 8 0
# sudo chown root.disk /dev/sdb
  ls -l /dev/sd*
# sudo mke2fs -text4 -LBCKUP1n /dev/sdb
# sudo mount -text4 /dev/sdb /run/media/moylan/BCKUP1n
  sudo wipefs -o 0x438 /dev/sdb

wipefs: error: /dev/sdb: probing initialization failed:
     Device or resource busy

df shows no sdb.  how can it be busy?  did i somehow
miscreate it?
