Among the security technologies we use are chroot, seccomp, and Linux namespaces. An AppArmor profile is installed in /etc/apparmor.d/usr.bin.fdns. The profile will kick in automatically on Debian and Ubuntu next time you start the computer. For systemd users, we provide a service file in /etc/fdns/fdns.service.
