    Starting jackd(bus) through set_rlimits is just one step. I wanted to
know how to pass realtime option (it's -R for jackd if I remember
correctly) when jackdbus accepts "auto" as the only argument (config file
or something?)

    Setting ladishd through set_rlimits would be the way to go, I think.

    No, that would be wrong. One would want only some apps/daemons with
rlimits.

    I think this is helpful, but I can not test it at work. I have
rehearsals and some work to finish, so I hope I'll get back to you with the
info this week. Thanx anyway!
