networks, mounts are ok, but how you are going to make sure that
a remote MySQL server is available from within a local init system?

With remote MySQL you cannot be even sure that MySQL is available
for a full run time of OpenDNSSEC, as there might be network breakages,
database might disconnect you due to capacity reasons, etc., the server
might be located after a HA proxy not handling TCP connection handovers.

So any software that rely on another networking server must be able
to cope with unavailability of the networked service.

E.g. instead of failing to start when MySQL is not available, it should
refuse to run the first operation in the queue until it is connected,
