+		       LINUX ALLOCATED DEVICES
+
+	 Maintained by H. Peter Anvin <[email protected]>
+
+		    Last revised: August 28, 1995
+
+This list is the successor to Rick Miller's Linux Device List, which
+he stopped maintaining when he lost network access in 1993.  It is a
+registry of allocated major device numbers, as well as the recommended
+/dev directory nodes for these devices.
+
+This list is available via FTP from ftp.yggdrasil.com in the directory
+/pub/device-list; filename is devices.<format> where <format> is txt
+(ASCII), tex (LaTeX), dvi (DVI) or ps (PostScript).  In cases of
+discrepancy, the LaTeX version has priority.
+
+This document is included by reference into the Linux Filesystem
+Standard (FSSTND).  The FSSTND is available via FTP from
+tsx-11.mit.edu in the directory /pub/linux/docs/linux-standards/fsstnd.
+
+To have a major number allocated, or a minor number in situations
+where that applies (e.g. busmice), please contact me.  Also, if you
+have additional information regarding any of the devices listed below,
+or if I have made a mistake, I would greatly appreciate a note.
+
+Allocations marked (68k) apply to Linux/68k only.

+	ADDITIONAL /dev DIRECTORY ENTRIES
+
+This section details additional entries that should or may exist in
+the /dev directory.  It is preferred that symbolic links use the same
+form (absolute or relative) as is indicated here.  Links are
+classified as "hard" or "symbolic" depending on the preferred type of
+link; if possible, the indicated type of link should be used.
+
+
+	Compulsory links
+
+These links should exist on all systems:
+
+/dev/fd		/proc/self/fd	symbolic	File descriptors
+/dev/stdin	fd/0		symbolic	stdin file descriptor
+/dev/stdout	fd/1		symbolic	stdout file descriptor
+/dev/stderr	fd/2		symbolic	stderr file descriptor
+
+
+	Recommended links
+
+It is recommended that these links exist on all systems:
+
+/dev/X0R	null		symbolic	Used by iBCS-2
+/dev/nfsd	socksys		symbolic	Used by iBCS-2
+/dev/core	/proc/kcore	symbolic	Backward compatibility
+/dev/scd?	/dev/sr?	hard		Alternate SCSI CD-ROM name
+
+
+	Locally defined links
+
+The following links may be established locally to conform to the
+configuration of the system.  This is merely a tabulation of existing
+practice, and does not constitute a recommendation.  However, if they
+exist, they should have the following uses.
+
+/dev/mouse	mouse port	symbolic	Current mouse device
+/dev/tape	tape device	symbolic	Current tape device
+/dev/cdrom	CD-ROM device	symbolic	Current CD-ROM device
+/dev/modem	modem port	symbolic	Current dialout device
+/dev/root	root device	symbolic	Current root filesystem
+/dev/swap	swap device	symbolic	Current swap device
+
+/dev/modem should not be used for a modem which supports dialin as
+well as dialout, as it tends to cause lock file problems.  If it
+exists, /dev/modem shold point to the appropriate dialout (alternate)
+device.
+
+
+	Sockets and pipes
+
+Non-transient sockets and named pipes may exist in /dev.  Common entries are:
+
+/dev/printer	socket		lpd local socket
+/dev/log	socket		syslog local socket
