Hi,
I have found a somewhat relevant discussion on the list archive, which dates
back to 2005:
https://sourceforge.net/p/bacula/mailman/message/14923506/
This clarified some of the questions about priority in the pattern matching
process but still for majority of my questions it does not provide answers.
Thanks,
Ivan
