   The CLIP OS project is an open-source project designed by the National Cybersecurity Agency of France (ANSSI) that aims to build a hardened, multi-level operating system, based on the Linux kernel and a lot of free and open source software.

   [...]

   The project is based on Gentoo Hardened and has many similarities with Chromium OS or the Yocto project.
