ubuntustudio-audio, ubuntustudio-controls and jackd installation scripts redundancies in 10.04

I did a fresh install of ubuntu lucid lynx.

I install ubuntustudio-audio metapackage, which installs jackd and many others

jackd_0.118+svn3796-1ubuntu2_i386.deb
ubuntustudio-audio_0.70_i386.deb
ubuntustudio-controls_0.4.7_all.deb

jackd postinst script writes:

@audio - rtprio 99
@audio - memlock unlimited
#@audio - nice -19
in
/etc/security/limits.d/audio.conf

This should deprecate the script rtprio.py in the ubuntustudio-audio package,
which writes:

@audio - rtprio 99
in
/etc/security/limits.conf

In addition, changes made for memlock and nice values in ubuntustudio-controls
affect /etc/security/limits.conf

imho, ubuntustudio-controls should be revised and ubuntustudio-audio script removed.
jackd postinst script seems more adequate to achive the needed privileges that jackd needs.
