[pkg-bacula-devel] Bug#825064: Bug#825064: Bacula director does not start silently due to database mismatch

it doesn't delete the database on upgrades. This is the description,
taken from /etc/dbconfig-common/bacula-director-sqlite3.conf:

# dbc_install: configure database with dbconfig-common?
#              set to anything but "true" to opt out of assistance

Admittedly, the documentation of that variable is a bit lacking, but if
this is 'false', dbconfig-common will not touch the database in any
case. See also:

https://lists.debian.org/debian-mentors/2010/04/msg00200.html

It wouldn't make any sense to reinstall the database on updates,
especially without asking.

If you want, I'll ask the maintainer of dbconfig-common for help on this
issue.

The dangerous operation would be to "dpkg-reconfigure
bacula-director-sqlite3" and then answer "yes" to the question of you
want to reinstall the database.
