What does the "al" in "alarm", the default Arch Linux ARM processor username+password stand for? ARM machines often have a default password. On Arch Linux, this is: User: alarm Password: alarm I am assuming that the "arm" part of "alarm" refers the architecture, but what does the "al" stand for? Perhaps I am completely off on my assumption.

The `al` part stands for Arch Linux, the `arm` part for ARM as you surmised.
