You are an Ubuntu user who has heard about this new OS called Haiku, and would like to try it out. You also like to be in the bleeding edge, so you don't want to settle for an alpha 1 release that has started to show signs of age (it dates back to September of 2009). Nor do you want to use the Haiku nightly builds, as they are too barebone and lacking even in very basic applications. If that's your case, then creating a Haiku install CD from the development branch is well worth a try, and not that difficult. This is a simple how to that describes, step-by-step, how to build a Haiku GCC2/4 hybrid install CD from the development tree using Ubuntu 9.10.
