On Arch Linux, I go to /etc/rc.d and remove or modify any scripts, which are clearly labelled.
On Ubuntu, I think I need to weed through the dozen or so numbered /etc/rc directories and find what I need and modify. I got pretty frustrated about this.
I don't know where I'm going to be able to modify the modules that get run when my computer starts on Ubuntu, but with Arch, there is a clearly labeled array in the rc.conf file called modules.
It just seems like looking under the hood of ubuntu is something I'm not supposed to do, and arch requires you to when you install it, but it is tremendously simple.
I want to switch back.
