Yes, correct.  However, your email wasn't as explicit so I didn't take proper 
notice.

The above is not really a bug, but let's say a design flaw in that two things 
are going on here:

1. In 1.38.x only drive 0 was unloaded during an "update slots" command and 
any drive specified was ignored.  During an "update slots" Bacula probably 
never should have unloaded any drives, but that's what it does.

2. If you were doing an "update slots scan" then drive 0 probably will be 
unloaded (I haven't looked at the code), but Bacula *should* use the drive 
specified if any for reading the Volume labels (I haven't looked at the 
code).

In version 1.39.22 and above, Bacula should not unload any drive during an 
"update slots" command, and hopefully (I haven't tested it) it will only 
access the drive you specify (if any) if you do "update slots scan".

So the output you list above is perfectly normal given the design of 1.38.
