 %description -n udev%{?mini}
-Udev creates and removes device nodes in /dev for devices discovered or
-removed from the system. It receives events via kernel netlink messages
-and dispatches them according to rules in %{_udevrulesdir}/. Matching
-rules may name a device node, create additional symlinks to the node,
-call tools to initialize a device, or load needed kernel modules.
+This package provides systemd-udevd. The udev daemon receives device uevents
+directly from the kernel whenever it adds or removes a device from the system in
+/dev, or it changes its state. When udev receives a device event, it matches its
+configured set of rules, located in %{_udevrulesdir}/, against various device
+attributes to identify the device. Rules that match may adjust device node
+permissions, create meaningful symlink names or provide additional device
+information to be stored in the udev database.
+
+The udev daemon may also rename network interfaces and perform various network
+device configurations, see systemd.link(5) for more details.
+
+This package also provides various tools and services that operate on devices
+exclusively. For example it contains systemd-cryptsetup to manage encrypted
+block devices as well as systemd-growfs to instruct the kernel to grow the
+mounted filesystem to full size of the underlying block device.
+
+This package shouldn't be necessary in containers.
