 Quick Install Guide
---------------------

1) in /usr/src/linux/include/linux/capability.h find these lines

#define CAP_INIT_EFF_SET    to_cap_t(~0 & ~CAP_TO_MASK(CAP_SETPCAP))
#define CAP_INIT_INH_SET    to_cap_t(0)

   and change them to

#define CAP_INIT_EFF_SET    to_cap_t(~0)
#define CAP_INIT_INH_SET    to_cap_t(~0)

   then recompile your kernel and boot it.  (Note that the above lines
   are from linux 2.4.19; it may be different if you're using a
   different version)

   NB: This may expose your system to local denial of service attacks.
   If it is a shared system or server, you should assess the impact of
   enabling capabilities in the context of your overall system security
   requirements.

2) install libcap from
   ftp://ftp.kernel.org/pub/linux/libs/security/linux-privs/kernel-2.4/

3) if you're using a journalling filesystem, mount some directory with
   -t tmpfs and tell configure about it with --with-default-tmpdir

4) configure with --enable-optimize --enable-capabilities and
   --with-default-tmpdir=/where/ever

5) make

6) as root, do 

       make install

7) create a .asoundrc file in your home directory like this:

------ 8< ----------- 8< ------

pcm.SOMENAME {
    type hw
    card 0
}

ctl.SOMENAME {
    type hw
    card 0
}

------ 8< ----------- 8< ------

8) run the jack server with:

      jackstart -R -d alsa -d SOMENAME
