-# This awk-script is the rule-base used in previous release for creating
-# compatibility-mode names.
-#
-#	WARNING: these rules are no longer used by default.  ucblinks
-#	is now a binary, not a script.  This rule-base can still
-#	be used, however, by running ucblinks with the option
-#	"-e /usr/ucblib/ucblinks.awk".  See the ucblinks(1B) man
-#	page for more information.
-#
-# The idea is to create the names as symbolic links to their SunOS5
-# counterparts by preference.  If no counterpart exists a direct link to the
-# devfs "/devices" directory is made.
-#
-# It does this base on input of the existing devices in the system.
-# The format of the input file is:
-#
-# driver-name \t minor number \t [b|c] \t /devices-name \t first-minor-component
-#
-# That is,
-#
-#	$1	driver-name
-#	$2	minor number
-#	$3	b(lock) or c(haracter) device
-#	$4	devices-directory name; relative to /dev (../devices/xxx)
-#	$5	first minor component name (string between ':' and nextr ','
-#		in last path-component of the /devices-name)
-#
-# and these are referred to throughout the script.
-#
-# The output of the script-rules are lines of the form:
-#
-# devname["device-link-fullname"] = "compatname";
-# devdir["device-link-fullname"] = "compatdir";
-#
-# The device-link-fullname should be relative to the directory in which the
-# SunOS5 link is expected to be found.  'compatdir' is that directory name,
-# FOLLOWED BY A SLASH.  'compatname' is the compatability name that should be
-# generated.
-#

-# The following devices need no changes, since the 4.x and 5.x names

- * ucblinks - create 4.x /dev compatibility names
- *
- * The basic algorithm is:
- *
- *	find block and character special files in /devices with major
- *	numbers of devices that need compatibility names
- *
- *	determine compatibility names from minor number, driver name, and
- *	/devices name
- *
- *	create symlinks for the compatibility names to 5.x /dev
- *	entries if possible or /devices entries if necessary
- *
- * The name space that ucblinks creates has a number of problems.
- * Unfortunately people have, to an unknown extent, come to depend
- * on the broken name space.  Fixing ucblinks to be more compatible
- * with 4.x would make it less compatible with previous releases of
- * 5.x.  The places were it is broken are noted throughout the code
- * and summarized here:
- *
- *	1157501 ucblinks creates completely broken 4.x links for IPI
- *	1157616 ucblinks does 0 <-> 3 swap for disks when it shouldn't
- *	1157617 ucblinks creates /dev/rxt* names instead of /dev/rmt*
- *	1157970 ucblinks creates incompatible and overlapping links for tapes

-# The rest of this script looks a mess.  But in fact underneath all the
-# 'sed's and 'awk's it is quite simple.
-#
-# First it creates a list of all the device nodes in the /devices directory
-# (by cd'ing to /dev, then doing a 'find' of all special files in ../devices
-# doing an 'ls -l' of these files, and sedding the output to produce a list
-# of the form 'major minor type name').
-#
-# As an added wrinkle it changes 'major' from a number to a driver-name using
-# sed rules produced from the "/etc/name_to_major file.
-#
-# Then it runs the awk rules in the rule-base on this list to produce a list
-# of compatability-links that must be created.  However, this does not produce
-# the links themselves because of the next stage:
-#
-# Finally this list of compatability-links is inspected and where possible links
-# to the SunOS5 names are created instead of links directly to the /devices
-# directory
-# (by 'find'ing all the symbolic links under /dev, ancomparing the
-# subdirectory they occur in, and the file to which they point, to
-# the comaptability-link information built above. If a match is found
-# a command to make a link to the 5.0 link, rather than to the /devices
-# entry, is created.  If not, a direct link is created)
-# And then the list of link command is executed by a shell, or printed on stdout
-# (in debugging mode)
-#
-# See -- not so complicated!  However the syntax of all these rules makes
-# the code below nearly incomprehensible.  Fear not; the only part you need
-# to change for extra devices is located in the 'RULEBASE' file.
