Saluki is an ultralight Linux distro with an XFCE desktop based on Puppy Linux.
While Puppy Linux is designed to resurrect old hardware, Saluki is designed with newer hardware, netbooks, and modern processors in mind.
The goal is a lightweight, easy to use, high performance OS that works out of the box with minimal configuration. It is small enough to run completely from RAM or boot from and save changes to USB sticks or rewritable CDs. It can also be installed alongside other OSes without partitioning the hard drive.
Saluki, like Puppy, runs in single user mode. It is primarily intended for single user computers where speed, simplicity, productivity, and convenience is paramount. It never asks for passwords unless encryption is enabled.
If you'd like to build your own custom lightweight OS, Saluki can easily be remastered with custom applications, custom kernels, and custom artwork
