That did exactly what I was looking to do. But it | had minimal impact on bootup time.

Glad I found out about it. I've | been picking away at a script that captures live data from a Linux | system prior to shutting it down (for a post mortem forensic analysis | of it). The output of this command with the --list option would be of | value to capture. Well, my laptop actually looks like this: [~]#root@zoob*> chkconfig --list|wc -l 151 [~]#root@zoob*> chkconfig --list|grep :on [~]#root@zoob*> I've turned it all off, and instead do this: [~]#root@zoob*> cat /etc/rc.local #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local ( . /opt/css/env.sh exec 2>/dev/tty2 exec rc.mobile \ start \ -f /etc/rc.mobile/conf \ -E /etc/rc.mobile/env.sh \ -E /u/cameron/var/env.sh \ @home-wifi ) rc.mobile is described here: http://www.cskk.ezoshosting.com/cs/css/rc.mobile.html The example config files are a little dated, but the idea is unchanged - start everything stuff in parallel, with a dependency scheme if one service needs another. Now my startup is most annoying in the speed of /etc/rc.sysinit, which takes a very long time, largely modprobing which seems rather inefficient (grep, modprobe single-module, grep...) Chuck a "set -x" at the top of /etc/rc.sysinit and see where it slows up.

Advantages: Will usually fix error. Disadvantages: 'Fix' is defined VERY loosely here. Symptoms: A tendancy to delete lines that get errors instead of fixing them. Real Case: One user complained that their program executed, but didn't do anything. The scon looked at it for twenty minutes before realizing that they'd commented out EVERY LINE. The user said, "Well, that was the only way I could get it to compile."
