+       help
+         This creates a tmpfs filesystem, and mounts it at bootup
+         and mounts it at /dev. The kernel driver core creates device
+         nodes for all registered devices in that filesystem. All device
+         nodes are owned by root and have the default mode of 0600.
+         Userspace can add and delete the nodes as needed. This is
+         intended to simplify bootup, and make it possible to delay
+         the initial coldplug at bootup done by udev in userspace.
+         It should also provide a simpler way for rescue systems
+         to bring up a kernel with dynamic major/minor numbers.
