Binary package “udev” in ubuntu-leb oneiric
rule-based device node and kernel event manager
udev is a collection of tools and a daemon to manage events received from
the kernel and deal with them in user-space. Primarily this involves
creating and removing device nodes in /dev when hardware is discovered or
removed from the system.
.
Events are received via kernel netlink messaged and processed according to
rules in /etc/udev/rules.d and /lib/udev/rules.d, altering the name of the
device node, creating additional symlinks or calling other tools and programs
including those to load kernel modules and initialise the device.
