Note. This documentation is outdated. Udev on modern distributions auto-detect the DVB devices. TODO: change this document to explain how to make DVB devices persistent, as, when a machine has multiple devices, they may be detected on different orders, which could cause apps that relies on the device numbers to fail.

udev executes entirely in user space, as opposed to devfs's kernel space. One consequence is that udev moved the naming policy out of the kernel and can run arbitrary programs to compose a name for the device from the device's properties, before the node is created; there, the whole process is also interruptible and it runs with a lower priority.Developer(s): Greg Kroah-Hartman and Kay Sievers

Dec 18, 2009 · Udev is the device manager for the Linux 2.6 kernel that creates/removes device nodes in the /dev directory dynamically. It is the successor of devfs and hotplug. It runs in userspace and the user can change device names using Udev rules. Udev depends on the sysfs file system which was introduced in the 2.5 kernel.Author: Unnikrishnan

The creation of these nodes is directed by the application of udev rules in user space. These rules are processed on udev events sent from the kernel directly as a result of adding, removing or changing particular devices. This provides a convenient and central mechanism for hotplugging support.

The device nodes in the /dev directory provide access to the corresponding kernel devices. With udev, the /dev directory reflects the current state of the kernel. Every kernel device has one corresponding device file. If a device is disconnected from the system, the device node is removed.
