Okay, I think I understand better, thank you for clarifying. I spoke about
it with the other engineer involved and we think we are going to automate it
but first put in some pre-checks before it sends an alert out. Im not sure
what those are yet, but with the snmp mod, nagios snap in, and the info
coming from the /proc/drbd I think we will be able to 'validate' that it
should become primary and then have the script start it else send us an
email alert for notification.
I will end up with probably about 75-100 of these deployed around different
segments of the country thus everytime one reboots, or loses power I don't
need a service call to ssh in and start it.

just because the snippet of the example config,
that I dared to cite, mentions GFS,
and you don't use GFS,
does not mean that you would have to do "manually"
or by handcrafted additional scripts
what this options is intended for:
you chose in configuration
one or both nodes
to be switched to primary
by the init script
right after configuration.
this does not mean that I think it is a good idea.
just that, when you really want to do this,
it is there already,
and you do not have to reinvent it, you can just use it.
