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
# fi
#done
