im trying to get as fast a boot from my system as possible. are there any tweaks i can make to the following files to get more speed.

here is my bootchart

here is my rc.multi

#!/bin/bash
#
# /etc/rc.multi
#

. /etc/rc.conf
. /etc/rc.d/functions

# Load sysctl variables if sysctl.conf is present
[ -r /etc/sysctl.conf ] && /sbin/sysctl -q -p &>/dev/null

# Start daemons
#for daemon in "${DAEMONS[@]}"; do
#    if [ "$daemon" = "${daemon#!}" ]; then
#        if [ "$daemon" = "${daemon#@}" ]; then
#            start_daemon $daemon
#        else
#            start_daemon_bkgd ${daemon:1}
#        fi

have a look at this wiki page http://wiki.archlinux.org/index.php/Twe … _boot_time
and Duologics forum post that led to the page's creation http://bbs.archlinux.org/viewtopic.php?id=62518.
