I have been trying to use Puppet to install the Zabbix server, which uses
dbconfig-common to set up its database.
If you don't do anything more than package { "zabbix-server-mysql": ensure
=> installed }, then you end up with errors that look much like this
(snipped for brevity) :
err: //zabbix::server/Package[zabbix-server-mysql]/ensure: change from
purged to present failed: Execution of '/usr/bin/apt-get -q -y -o
DPkg::Options::=--force-confold install zabbix-server-mysql' returned 100:

In short, it's expecting that you have answered questions about its MySQL
root password.
If you install the package manually, the first question you are asked is
whether or not you want to use dbconfig-common, and a warning that if you
already have a database set up, you don't want to use it. It seem to
influence the value for the dbconfig-install key. Therefore, it stands to
reason that if I preseed this key:
zabbix-server-mysql zabbix-server-mysql/dbconfig-install boolean false
then I should get what I want. However, I don't - still prompted, still
fails to install silently, etc.
As this question probably comes up a lot for people installing software
through Puppet, has anyone come up with a satisfactory solution to tell
debconf/dbconfig-common to just get out of the way entirely?
