Thanks!

Since I don't have an F14 system to test on (still need to upgrade my
desktops), I loaded it up in MeeGo 1.2
[2.6.38.2-8.6-adaptation-pinetrail] ( which is somewhat compatible w/
Fedora 14 i686 ... see http://wiki.meego.com/MeeGo-Lem ) and did a
brief test against mixxx(1) and it worked. I figure Koji doesn't need
any cross-distro voting, so I'll just report my experience here....

One of the things I noticed is that /etc/security/limits.conf doesn't
get set by this version of jack, however, it seems the settings
normally put in there are ignored anyways.

In this current version, without customizing /etc/group, you get
"cannot lock down memory area" message:
.................
jackdmp 1.9.7
[...]
no message buffer overruns
no message buffer overruns
JACK server starting in realtime mode with priority 20
Cannot lock down memory area (Cannot allocate memory)
....................

To prevent the problem, in /etc/group, add he username (npm in my
case) to the jackuser group:
..................
jackuser:x:495:npm
..................

Then logout/login and try again. Now, I get the following results with
the builtin-audio on this Lenovo s10-3t touchscreen netbook (n.b. the
touchscreen is awesome for music).
