Boot Process Help
I'm trying to make my boot up as minimal as possible, but I'm running into a few problems.
This is my current bootchart.
Can someone help me find out why udevd runs twice? Is kthreadd controlled by the kernel?
Load-modules.sh is symbolically linked to modprobe.
These are my init scripts:
rc.sysinit:
#!/bin/bash
#
# /etc/rc.sysinit
#
. /etc/rc.conf
. /etc/rc.d/functions
# bring up the loopback interface
if [ -d /sys/class/net/lo ]; then
stat_busy "Bringing up loopback interface"
/sbin/ifconfig lo 127.0.0.1 up
if [ $? -ne 0 ]; then
stat_fail
else
stat_done

Re: Boot Process Help
I've already read though that and haven't found any answers. 
Also my rc.sysinit is based off quick-init. I just didn't like the renaming of the scripts and also it's a package I don't need.
