[Opendnssec-user] dendency wrong in ubuntu packages

[Ondřej Surý]

Hi Bas,

this has to be solved in OpenDNSSEC itself.

While I could in theory add:

Required-Start: $mysql

to init scripts that would only work:

a) if mysqld actually starts to listen before opendnssec is started
(f.e. it could start checking the databases in background, etc.)
(fortunately in this case, the Debian init.d scripts waits for MySQL to
become available)
b) if mysql is running on the same machine

Therefore OpenDNSSEC needs to be able to cope with MySQL not running and
start the daemon, but wait for MySQL to become available before doing
anything, instead of failing.

Also don't think that init daemons generally has option to wait for
MySQL only if MySQL is actually installed. With Debian insserv it would
probably work, because the "Required-Start:" would get probably ignored
if not available. But with upstart or systemd this is not possible and
it's up to the local administrator to configure the daemons to run in
correct order.

Cheers,
