Kevux is an operating system based mainly on GNU operating programs and a Linux kernel, all compiled with uclibc instead of the more common glibc. It is not FHS or LSB compatible. Compared to other Linux distributions, Kevux is space efficient (making it suitable for USB disk operation) and difficult to hack into.
