Firejail is a SUID program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces and seccomp-bpf. It allows a process and all its descendants to have their own private view of the globally shared kernel resources, such as the network stack, process table, mount table. This is long term support branch of firejail. For the regular version see sys-apps/firejail. The code base is approximately 40% smaller than the regular version, providing a smaller attack surface for the SUID executable.
