Ill attach my bootchart so you guys can see what daemons, modules are loading etc.
Any extra tips or tricks, or things i can disable that will help me get under that 20 second mark?

Hi

well, for example you can gain some speed by tweaking your inittab.

1. switch off unneeded ttys/consoles
2. replace all statements with "wait" by "once"
3. replace getty by smaller and faster mingetty (or alike) - beware: install it first!!

then your inittab should more or less like mine:

# /etc/inittab: init(8) configuration.
# $Id: inittab,v 1.91 2002/01/25 13:35:21 miquels Exp $

# The default runlevel.
id:2:initdefault:

# Boot-time system configuration/initialization script.
# This is run first except when booting in emergency (-b) mode.
si::sysinit:/etc/init.d/rcS

# What to do in single-user mode. / mic: replaced wait by once
~~:S:once:/sbin/sulogin

# /etc/init.d executes the S and K scripts upon change
# of runlevel.
#
# Runlevel 0 is halt.
# Runlevel 1 is single-user.
# Runlevels 2-5 are multi-user.
# Runlevel 6 is reboot.

#  / mic: replaced all wait by once

l0:0:once:/etc/init.d/rc 0
l1:1:once:/etc/init.d/rc 1
l2:2:once:/etc/init.d/rc 2
l3:3:once:/etc/init.d/rc 3
l4:4:once:/etc/init.d/rc 4
l5:5:once:/etc/init.d/rc 5
l6:6:once:/etc/init.d/rc 6
# Normally not reached, but fallthrough in case of emergency.
z6:6:respawn:/sbin/sulogin

# What to do when CTRL-ALT-DEL is pressed.
ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now

# Action on special keypress (ALT-UpArrow).
#kb::kbrequest:/bin/echo "Keyboard Request--edit /etc/inittab to let this work."

# What to do when the power fails/returns.
pf::powerwait:/etc/init.d/powerfail start
pn::powerfailnow:/etc/init.d/powerfail now
po::powerokwait:/etc/init.d/powerfail stop

# /sbin/getty invocations for the runlevels.
#
# The "id" field MUST be the same as the last
# characters of the device (after "tty").
#
# Format:
#  <id>:<runlevels>:<action>:<process>
#
# Note that on most Debian systems tty7 is used by the X Window System,
# so if you want to add more getty's go ahead but skip tty7 if you run X.
#
#  / mic: only 2 ttys left / replaced getty by mingetty / delete baudrate

1:2345:respawn:/sbin/mingetty tty1
2:23:respawn:/sbin/mingetty tty2
#3:23:respawn:/sbin/mingettygetty tty3
#4:23:respawn:/sbin/mingetty tty4
#5:23:respawn:/sbin/mingetty tty5
#6:23:respawn:/sbin/mingetty tty6

ps. let me know the gain in speed...
