Do you remember "jackstart" and the Capabilities-hack? This is replaced by the PAM module pam_limits now. The don't give you better realtime performance itself, they just allow non-root users to run with higher priorities or nice values and do the memory lock to avoid swapping. > Second, do I need to compile anything other than ALSA for audio/MIDI > USB support ? No. Just make sure, you don't build the OSS modules or blacklist them in /etc/hotplug/blacklist > Finally, the build instructions still assume LILO.

If you build with make-kpkg (recommended!) you can do some configuration in "/etc/kernel-img.conf": postinst_hook=/sbin/update-grub postrm_hook=/sbin/update-grub This will update your grub-loader automatically, once you install a new kernel image from a Debian package.
