Kuki Linux
Kuki Linux is a lightweight Ubuntu-based Linux distribution founded by João Ferro (leak), built to be a replacement for the Linpus Lite distribution on the Acer Aspire One.
João’s goal for Kuki Linux are :
Out of the box working system
Fast boot and low usage on SSD / HDD
Light and fully working programs for most common daily tasks.
Kuki Linux is built by a small team of developers: João Ferro (leak) , Joseph Braddock (vw72). It uses XFCE 4.6 as a window manager and features lightweight software and all the fixes to allow the Acer Aspire One to work as well as possible.
It is supported by a great bunch of people in the IRC room #kukilinux on irc.freenode.net.
