ENG Christian Brauner: Making the Kernel and Udev Namespace Aware / #LinuxPiter

Making the Kernel and Udev Namespace Aware On non-embedded systems device management in Linux is a task split between kernelspace and userspace. Since the implementation of the devtmpfs pseudo filesystem the kernel is solely responsible for creating device nodes while udev in userspace is mainly responsible for consistent device naming and permissions. The devtmpfs filesystem however is not namespace aware. As such devices always belong to the initial user namespace. In times of SR-IOV enabled devices it i
