Ubuntu has gained enormous popularity, since Canonical first released Ubuntu back in 2004. There were a lot of Ubuntu spin-off along the way including Ubuntu Christian edition, Ubuntu studio, Embun, Kubuntu, Xubuntu, Edubuntu, Ubuntu Muslim Edition, Linux Mint, gOS and many more. Some of it made its way as the officially supported Ubuntu version by Canonical.
Now comes yet another Ubuntu-based Linux distribution, named Minibuntu. What set itself apart from other distro is, it does not come with a window manager, instead it boots straight into command-line interface bash prompt.
This makes minibuntu suitable for acting as a rescue and emergency Linux boot CD, eventhough the main intention of minibuntu is to help others to create another Linux distribution based on Ubuntu using either UCK or Reconstructor.
To me, Miniubuntu is a nice distro as it provide a starting point for creating a new and customised Linux distribution based on Ubuntu.
Minibuntu can be downloaded from its official website, and is only available for i386 platform only (at this time of writing).
