Usage: $PROGNAME DIRECTORY
This script will create base device nodes and symlinks in directory DIRECTORY.
These device nodes and symlinks will be sufficient for initial system boot
prior to udev starting, chroot-based environments, and container environments
such as OpenVZ, in a situation where the user chooses not to use udev.
This script is also used by the udev ebuild to populate /lib/udev/devices,
which contains the initial set of device nodes that are copied to /dev by
udev when it starts.
This script will not replace existing device nodes with new device nodes.
However, if a non-device exists where a device should exist, the non-device
will first be removed and the device node will be created in its place with
standard permissions. This is useful in situations where invalid /dev/null or
similar files may be exist - they will be replaced with proper device nodes.
Symbolic links are created with the -f option, so any destination files
or devices that exist in the directory will be removed first if they exist.
