Summary:                    Cannot backup to a subdirectory of a mounted file
system.
Description: 
If a device is configured with the archive device as a subdirectory of the mount
point and "Requires Mount = yes", the storage daemon keeps issuing an error (no
such file or directory) and there is no possibility for a backup to succeed.

I suspect the existence of the "Archive Device" directory is monitored BEFORE
issuing the "Mount Command", thus preventing to see the effective directory
hierarchy.

As a proof and workaround, if I create the (empty) target "Archive Device"
directory on the bare (i.e.: unmounted) mount point, the problem disappears and
the backup is effectively stored on the mounted file system.

Steps to Reproduce: 
Device {
  Name = NAS
  Media Type = File
  Archive Device = /media/backup/bacula
  Mount Point = /media/backup
  Requires Mount = Yes
  Mount Command = "sudo mount -t cifs -o <<<options>>> //machine/export %m"
  Unmount Command = "sudo umount '%m'"
  LabelMedia = yes;                   # lets Bacula label unlabeled media
  Random Access = Yes;
  AutomaticMount = yes;               # when device opened, read it
  RemovableMedia = no;
  AlwaysOpen = no;
}

Please note the "Archive Device" and "Mount Point" in the configuration above.

Additional Information: 
The Mount Point directive was written for DVD devices which we no longer
support. It was never implemented for files, so this request is really a feature
request.

I can admit that it would be nice to have, but it is code needs to be
implemented.  

For the moment, the only workaround you have is to mount the NAS (I assume)  and
make sure the Archive Device is always available prior to starting the job.
