Devil-Linux is a minimal distribution designed to run on firewalls and routers. After many years of operating, the Devil-Linux project is being shut down. Heiko Zuerker posted to the project's mailing list: "Unfortunately, after almost 20 years, I have to officially stop releasing new versions of Devil-Linux. I simply do not have the time anymore to do this properly. This is in addition to GRSecurity not being available anymore to the general public, which was the core of our security features. It has been a blast maintaining this distro and we had a lot of long-term followers, for which I am very grateful. All current downloads and the sources will of course stay on the websites."
