IronBox Linux is a Linux distribution based on Linux From Scratch and designed for usage in high security server environments. Its main goal is to ensure a stable and secure deploy where patching and system upgrades do not depend on security bugs, but on the task team schedules and the needed features of the system or the software it runs.
KaufKauf Slim Linux is a fully configured Linux-based operating system that is able to run from flash memory. It doesn't require more than 700 MBytes of disk space.
