By "built in" I mean configured as "Y" rather than the usual "M".  I
mentioned that because Nando was having some problems doing that on
CCRMA with FC3 due to conflicts with the built in capability LSM.
Currently, LSM stacking does not work smoothly.

You have to patch first before the security options will appear.

To apply the patch...

  $ cd /usr/src                         # (or wherever you like)
  $ tar xjf linux-2.6.10.tar.bz2        # (from kernel.org)
  $ cd linux-2.6.10
  $ patch -p1 < /path/to/patch/file

Configure and build the kernel...

  $ make xconfig
  $ make bzImage
  $ make modules

Then (as root) install and update LILO or GRUB.

The parameters are explained in `Documentation/realtime-lsm.txt'.
With the LSM built in, you'll probably want to set parameters via
sysfs (as root), using either...

  # echo 1  > /sys/module/realtime/parameters/any


  # echo 29 > /sys/module/realtime/parameters/gid

Pick any group ID you like (29 is the Debian `audio' group).
