Como hacer mas rapido el boot 'eo ala hora de Iniciar nuestro Slackware

Bueno como lo acabo de hacer, y tal vez muchos usuarios de slackware ya lo han hecho pero no lo han publicado, se puede comentar mucho pero sere breve como siempre.

la solucion de hacer posible esto de una manera sencilla es editando el archivo /etc/rc.d/rc.M mandando algunos script o conocidos como demonios iniciarlos background y como es posible hacer esto? bueno en bash hay un caracter que se utiliza de esta manera:

sh script.sh &

y directamente lo mandara a ejecucion background y te mostrara el prompt para seguir realizando tareas, se puede realizar en cualquier terminal..

bueno entonces estos son los archivos y los pegare ya editados por si quieren utilizarlos....


#!/bin/sh
#
# rc.M This file is executed by init(8) when the system is being
# initialized for one of the "multi user" run levels (i.e.
# levels 1 through 6). It usually does mounting of file
# systems et al.

# Initialize PCMCIA devices:
#
# NOTE: This used to be started near the top of rc.S so that PCMCIA devices
# could be fsck'ed along with the other drives. This had some unfortunate
# side effects, however, since root isn't yet read-write, and /var might not
# even be mounted the .pid files can't be correctly written in /var/run and
# the pcmcia system can't be correctly shut down. If you want some PCMCIA
# partition to be mounted at boot (or when the card is inserted) then add
# the appropriate lines to /etc/pcmcia/scsi.opts.
#
# Note that the stuff in /etc/pcmcia/ is only for 2.4.x kernels using
# 16-bit PCMCIA cards (not 32-bit Cardbus cards!). For example, with a
# wireless card you might need to set options in /etc/pcmcia OR in
# /etc/rc.d/rc.wireless.conf, or even in /etc/rc.d/rc.inet1.conf (with
# extra options if needed for the encryption key, ESSID, etc.)

#
# You'll then need to setup initial quota files at the top of the partitions
# to support quota, like this:
# touch /home/aquota.user /home/aquota.group
# chmod 600 /home/aquota.user /home/aquota.group
#
# Then, reboot to activate the system.
# To edit user quotas, use 'edquota'. See 'man edquota'. Also, the
# official Quota Mini-HOWTO has lots of useful information. That can be found
# here: /usr/doc/Linux-HOWTOs/Quota
