I did already report this finding in detail in my test reports in
bacula-devel.  If it SHOULD work, I will revert my configuration and
re-test.

What I found was that a tape could be read and written in a standalone
drive if already mounted when the SD was started, but could not be
mounted or unmounted except by stopping the SD and manually using mt.
Running the SD at -d 200, it appeared the SD never received the
mount/unmount commands.

The 'fake autochanger' workaround was suggested by Ana Arruda, who said:

"I don't remember in what version the old tape drive configuration in
bacula-dir.conf as a stand alone storage device was causing the
mount/unmount bconsole commands to do nothing and this is the workaround
we have to make it work."
