I'm a big fan of Arch Linux @l0k1 - Working with Arch Linux reminded me a lot of working with my first Linux distribution, Pygmy Linux, back in the 1990s. Pygmy Linux was a trimmed down spin of Slackware which provided users with a simple command line interface only, by default. There was no compiler, no package manager, no desktop environment. Everything was done manually or with hand-written scripts. Pygmy presented a steep learning curve when I was first introduced to Linux and Unix, and it was what I needed to become familiar with the technology and pass my course in operating systems at University.

Running Arch is something I think will appeal to people who like to build their operating systems rather than simply run them.
