These will look very similar to what you have here. I do not have a node
running olsrd_mdp in front of me, but here are the class of things that
you can expect to enter there:

servalpath will be like /etc/serval (as it is by default on Commotion
nodes). This contains a place for the keys to be stored and the
configuration values to be kept.

sid will be like
2A944A05906B6E676C8AE6747968F97ED6E564820CC18ADC34D6B597DE1AE658. This
is an identifier that tells the plugin which keypair to use for signing
routes. The key itself can be passed from node-to-node by copying the
serval.keyring file from the instance path directory.

Does this answer some of your questions?
