[PlanetCCRMA] jack not running

[Mark Knecht]

Fernando,
   OK, was jackstart something the Planet developed? Or was it supplied by
Paul?

   Most of the time I run as root, so I should just use jackd -R ...
instead?

Mark

"jackstart" is a small suid program that starts jackd with realtime
priority even when you run it as a non-root user (jackstart plus a
capabilities enabled kernel is what makes this trick possible).

When you see jackstart in the process list substitute jackd.
