As I heard from the Debian jackd maintainer:
In Debian testing/ squeeze and very likely in Ubuntu lucid, it's not
neccesary anymore to manual edit /etc/security/limits.conf! It's been
automatically done by jackd in /etc/security/limits.d/audio.conf and it
will conflict with /etc/security/limits.conf.
Such things are good to know if you're member of the LAU community, and
I feel communication is lacking often with these kind of things...
