High:
 * add native systemd support
   - execute config test in ExecStartPre=
   - see https://www.freedesktop.org/software/systemd/man/systemd.service.html

Normal:

 * Unify bacula-sd-(pgsql|mysql|sqlite3) into bacula-sd-tools, they
   all have the same content
 * Check if bacula-director-pgsql suggesting postgresql-contrib is useful

Wishlist:

 * autopkgtests
 * reproducible builds

Old:

* Maybe:
  
  Remove old AUTHFILE=`getent passwd bacula | cut -d ':' -f 6`/.pgpass
  and $AUTHFILE.bak
