Hello all.
Some notes taken from jackd manpage that cover a few of the topics in your
mail here:
Every JACK client reads environment variables under the hood that can
control some of the aspects you refer to.
$JACK_DEFAULT_SERVER specifies the default server name.
As an example:
JACKD_DEFAULT_SERVER=nondefault jack_lsp
jack_lsp doesn't need special code for handling for that.
$JACK_NO_START_SERVER specifies to not start a server when none is running
(with given name).
As Nettingsmeier pointed out, you really want to start the server
separately with defined parameters and not rely on a client to do it.
Clients can control server name and autostartup behavior in code
explicitly by passing jack_options_t to the jack_client_open() function.
$JACK_PROMISCUOUS_SERVER allows for relaxed permissions, "allowing clients
from different users to talk with the same server"
Finally you can always wrap the server or client startups in a script or
have a small daemon that will do it iff the other approaches aren't good
enough.
Greetings
