Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

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.
