They are not hidden anywhere.

The QJackCtl setup dialog shows you ALL the parameters. JACK's default parameters are identified on the man page and they are very few.

In general, starting JACK at boot time is a mistake.

OK, just saw the -P option :)

Now it becomes very important to know where the heck the parameters for
launching jackd are hidden so that it can be started properly at boot.
I cannot use qjackctl since right now the buffer size defined in
qjackctl is 128 while clearly jackd is launched with -p256, from
Somewhere Else.
