Hello Dan, nice to see you.
Yes, 3:04 jobs will all start before any 3:05 jobs regardless of their priority.
It seems AllowMixedPriority only works when higher priority jobs are submitted
after lower jobs are already running, and never the opposite. At least it's
what I understand from (Kern's ?) comment in the the source code:
"bool allow_mixed_priority; /* Allow jobs with higher priority concurrently
with this */"
Other way to prioritize jobs without creating a critical path between them is
reorganizing their order like they appear in the bacula-dir.conf, I think even
if they are in included split files.
