List of default Ubuntu init scripts
It would be nice to have a complete list of default Ubuntu init scripts. Like that users can lookup which ones they can easily deactivate to speedup the boot process and save memory. This page could eventually merged with UbuntuBootupHowto.
There's also a page InitScriptHumanDescriptions now, which is more complete and aims to provide short, human-readable descriptors for init scripts.

FAQ
What are the different runlevels for?
- Runlevel 0 stands for shutdown
- Runlevel 2 is the default runlevel for the Ubuntu boot process
- Runlevel 6 stands far reboot
Why does Ubuntu uses runlevel 2 as default? Will I ever need 3-5?
What is in /etc/rcS.d?
- The links you find in there are executed before executing runlevel 1-5.
What does '''K''' and '''S''' stand for?
K stands stops a process, S starts it.
What do the numbers between '''K''' / '''S''' and the initscript name mean?
- these numbers determine the order in which the various scripts get executed. S35mountall.sh is executed before S40hotplug.
How do I deactivate a script at bootup?
