Once upon a time there was DSL (Damn Small Linux) which provided a full workable system in a 50 MB image. I used to have it on a small partition for repair and rescue tasks on my desktops. It was never or at least very rarely needed as I recall, but I liked the pre-set radio stations in XMMS and the backgrounds and conky config in DSL, so I ended up running it more and more over Zenwalk 2.6, which at the time was using a very half-baked early XFCE 4.4, if only to listen to internet radio on a geeky minimalistic looking box.
