MAKEDEV(8)			   BSD System Manager's Manual			       MAKEDEV(8)

     MAKEDEV -- create system and device special files

     MAKEDEV [-fMsu] [-m mknod] [-p pax] [-t mtree] {special | device} [...]

     MAKEDEV is used to create system and device special files.  As arguments it takes the names
     of known devices, like sd0, or of special targets, like all or std, which create a collec-
     tion of device special files, or local, which invokes MAKEDEV.local(8) with the all argu-

     The script is in /dev/MAKEDEV.  Devices are created in the current working directory; in
     normal use, MAKEDEV should be invoked with /dev as the current working directory.

     Supported options are:

     -f 	 Force permissions to be updated on existing devices.  This works only if MAKEDEV
		 invokes mknod(8); it is not compatible with the -p, -s, or -t options.

     -M 	 Create a memory file system, union mounted over the current directory, to con-
		 tain the device special files.  The memory file system is created using
		 mount_tmpfs(8) or mount_mfs(8), in that order of preference.

		 If the -M flag is specified more than once, then MAKEDEV assumes that it is
		 being invoked from init(8) to populate a memory file system for /dev.	In this
		 case, MAKEDEV will also redirect its output to the system console.

     -m mknod	 Force the use of mknod(8), and specify the name or path to the mknod(8) program.
		 [Usually, $TOOL_MKNOD or mknod.]

     -p pax	 Force the use of pax(1), and specify the name or path to the pax(1) program.
		 [Usually, $TOOL_PAX or pax.]

     -s 	 Generate an mtree(8) specfile instead of creating devices.

     -t mtree	 Force the use of mtree(8), and specify the name or path to the mtree(8) program.
		 [Usually, $TOOL_MTREE or mtree.]

     -u 	 Don't re-create devices that already exist.

     MAKEDEV has several possible methods of creating device nodes:

     o	 By invoking the mknod(8) command once for each device node.  This is the traditional
	 method, but it is slow because each device node is created using a new process.

	 The -m option forces MAKEDEV to use the mknod(8) method.

     o	 By internally creating a specfile in a format usable by mtree(8), and providing the
	 specfile on standard input to a pax(1) or mtree(8) command, invoked with options that
	 request it to create the device nodes as well as any necessary subdirectories.  This is
	 much faster than creating device nodes with mknod(8), because it requires much fewer
	 processes; however, it's not compatible with the -f option.

	 The -p or -t options force MAKEDEV to use the pax(1) or mtree(8) methods.

     o	 If the -s option is specified, then MAKEDEV will not create device nodes at all, but
	 will output a specfile in a format usable by mtree(8).

     The -m, -p, -s, and -t flags are mutually exclusive.  If none of these flags is specified,
     then MAKEDEV will use mtree(8), pax(1), or mknod(8), in that order of preference, depending
     on which commands appear to be available and usable.  In normal use, it's expected that
     mtree(8) will be available, so it will be chosen.	If MAKEDEV is invoked by init(8), it's
     expected that mtree(8) will not be available, but pax(1) may be available.

     The special targets supported on NetBSD are:

     all       Makes all known devices, including local devices. Tries to make the 'standard'
	       number of each type.
     init      A set of devices that is used for MFS /dev by init. May be equal to ``all''.
     floppy    Devices to be put on install floppies
     ramdisk   Devices to be put into INSTALL kernel ramdisks.
     std       Standard devices
     local     Configuration specific devices
     wscons    Make wscons devices
     usbs      Make USB devices
     isdns     Make ISDN devices

     The following environment variables affect the execution of MAKEDEV:

	     If this is set, then MAKEDEV will define several shell functions and then return,
	     ignoring all its command line options and arguments.  This is used to enable
	     MAKEDEV.local(8) to use the shell functions defined in MAKEDEV.

     /dev		 special device files directory
     /dev/MAKEDEV	 script described in this man page
     /dev/MAKEDEV.local  script for site-specific devices

     If the script reports an error that is difficult to understand, you can get more debugging
     output by using
	   sh -x MAKEDEV argument.

     config(1), pax(1), intro(4), diskless(8), init(8), MAKEDEV.local(8), mknod(8), mount_mfs(8),
     mount_tmpfs(8), mtree(8)

     The MAKEDEV command appeared in 4.2BSD.  The -f, -m, and -s options were added in
     NetBSD 2.0.  The -p, -t, and -M options were added in NetBSD 5.0.	The ability to be used as
     a function library was added in NetBSD 5.0.

     The -f option is not compatible with the use of mtree(8) or pax(1).

     Not all devices listed in this manpage are supported on all platforms.

     This man page is generated automatically from the same sources as /dev/MAKEDEV, in which the
     device files are not always sorted, which may result in an unusual (non-alphabetical) order.

     In order to allow a diskless NetBSD client to obtain its /dev directory from a file server
     running a foreign operating system, one of the following techniques may be useful to popu-
     late a directory of device nodes on the foreign server:

     o	 If the foreign server is sufficiently similar to NetBSD, run MAKEDEV in an appropriate
	 directory of the foreign server, using the -m flag to refer to a script that converts
	 from command line arguments that would be usable with the NetBSD mknod(8) command to the
	 equivalent commands for the foreign server.

     o	 Run MAKEDEV with the -s flag to generate an mtree(8) specification file; this can be
	 done on any host with a POSIX-compliant shell and a few widely-available utilities.  Use
	 the pax(1) command with the -w -M flags to convert the mtree(8) specification file into
	 an archive in a format that supports device nodes (such as ustar format); this can be
	 done on a NetBSD host, or can be done in a cross-build environment using
	 TOOLDIR/bin/nbpax.  Finally, use apropriate tools on the foreign server to unpack the
	 archive and create the device nodes.
