'''udev''' (userspace {{mono|[[devfs|/dev]]}}) is a device manager for the [[Linux kernel]]. As the successor of [[devfsd]] and hotplug, udev primarily manages [[device node]]s in the {{mono|[[devfs|/dev]]}} directory. At the same time, udev also handles all [[user space]] events raised when hardware devices are added into the system or removed from it, including [[firmware]] loading as required by certain devices.
