The boot process and how/where you can hack it.

1. BIOS (press F2 to setup)
2. GRUB loader (/boot/grub/menu.lst. see Install/run rescue console on the EEE )
3. kernel – see Rebuilding the kernel
4. initrd – see http://forum.eeeuser.com/viewtopic.php?id=2650 on how to hack initramfs-eeepc.img
5. /sbin/fastinit – this is a binary file and sources seems to be unavailable(?). YES, normal init and /etc/rc* directories are NOT used. by looking into fastinit (with strings), somewhere at the end it starts in background the following two processes

   su -c startx -l user &
   /usr/sbin/services.sh &

   Note: fastinit has been reimplemented for notes and code; see Eee fastinit reimplementation at hellabs.org.

6. /usr/sbin/services.sh – edit this to add “services” which start on boot
7. If you don't feel comfortable with editing /usr/sbin/services.sh, the script refers to a file called /etc/fastservices (doesn't exist by default). You can create or edit this file to add services to the bootup process, one line per service. For example if you have installed Openssh-server, you can add a line to /etc/fastservices simply containing the word ssh. The name you need to add is the name of the startup file for the service, as found in /etc/init.d. This will slightly increase the boot time, but you probably won't notice the difference.
8. startx → /usr/bin/startsimple.sh
