MAKEDEV(8)	     FreeBSD/amd64 System Manager's Manual	    MAKEDEV(8)

NAME
     MAKEDEV --	create system and device special files

SYNOPSIS
     MAKEDEV [name ...]

DESCRIPTION
     The shell script MAKEDEV, found in	the /dev directory, is used to create
     various special files.  See intro(4) for a	more complete discussion of
     special files.

     MAKEDEV takes any number of device	names as arguments, where the names
     are the common abbreviation for the device	or group of devices.  Files
     are created in the	current	working	directory.

     Where a device name is followed by	a star `*', the	star must be replaced
     by	a unit number.	If units are expected for a device but not provided,
     MAKEDEV will supply the standard numbers in most cases.

     The amd64 supports	the following devices:

     Special device names
     all	 Creates special files for all devices on amd64.
     ramdisk	 Ramdisk kernel	devices.
     std	 Creates the `standard'	devices	(console, klog,	kmem, ksyms,
		 mem, null, stderr, stdin, stdout, tty,	zero) which are	abso-
		 lutely	necessary for the system to function properly.
     local	 Creates configuration-specific	devices, by invoking the shell
		 file MAKEDEV.local.
