Hi Bill,

coming back to bacula-tapealert: when I try to use it from command line 
I get

/usr/libexec/bacula/bacula-tapealert.py:220: DeprecationWarning: 'count' 
is passed as positional argument
  st = re.sub('.*(/dev/)n(.*)', '\\1\\2', drive_device, re.S)

Independend if I use /dev/sg* or /dev/st0 /dev/nst0...

Not sure how to fix this

Cheers

T
