-OTP R4B b1 UnixWare Release Notes
-------------------------------------
-
-Kent Boortz
-
-This is an *unsupported* release of OTP to UnixWare 2.1.2.
-In fact, it should not be considered a release or a product at all,
-it is a demo what a real release could look like.
-
-Questions should be directed directly to
-
-	Kent Boortz
-	[email protected]
-
-Changes or problems:
-
-     *	There is no documentation as part of this release.
-	Use the R5B documentation that comes with the
-	Solaris release.
-
-     *	To run older graphical tools based on 'pxw' like
-	'xerl' and 'interpreter' you have to add
-	"/usr/X/lib" to your LD_LIBRARY_PATH.
-
-     *	The OTP test cases looks reasonable well considering the
-	short time I had to do the port. The tests of the base
-	system gives equal results than on Solaris. There are
-	some problems with the 'ic' application (CORBA) and there
-	may be some 'mnesia' problems (the tests where not completed
-	when I wrote this note)
-
-     *	OTP normally try to handle IP host name lookups
-	by itself, parsing /etc/hosts and other configuration
-	files. This is done because the normal calls like
-	gethostbyname() is blocking. In this UnixWare port
-	the normal gethostbyname() is used and if a reply
-	from the name server takes some time this may block
-	the OTP system from doing other tasks (it may be the
-	case that it doesn't block the whole system, it may
-	just keep other Erlang processes that do DNS lookups
-	waiting, I'm not sure).
-
-     *	The erl_interface library support varios types of threading
-	This is not supported in the OTP UnixWare release.
-
-     *	If you use gcc you compile and link dynamic drivers with
-
-		gcc -fPIC -c foo.c
-		ld -G -t text -o foo.so foo.o
-
-	With the UnixWare C compiler I belive it will be
-
-		gcc -KPIC -c foo.c
-		ld -G -t text -o foo.so foo.o
-
-     *	The default shell limits was a problem when I was running
-	some large tests. These limits can be changed by building 
-	a new kernel. To enable unlimited use of virtual memory
-	and data you do as root
-
-		% /etc/conf/bin/idtune SDATLIM 0x7FFFFFFF
-		% /etc/conf/bin/idtune HDATLIM 0x7FFFFFFF
-		% /etc/conf/bin/idtune SVMMLIM 0x7FFFFFFF
-		% /etc/conf/bin/idtune HVMMLIM 0x7FFFFFFF
-		% /etc/conf/bin/idbuild
-
-	When you reboot a new kernel will be built.
-	
-     *	I didn't give the system enough swap space. You can add
-	swap on an ordinary file. To add about 100 MB more swap
-	you do as root
-
-		% dd < /dev/zero > /moreswap bs=512 count=200000
-		% swap -a /moreswap 0 200000
-
-	The first line will create a 100 MB file on the root partition
-	and the second line will add this file as swap space. Note that
-	the "swap" command is a bit buggy and may hang. Reboot UnixWare
-	and try again.
-
-Internel notes on build the release
-
-     *	If the network addresses are changed you enter single user
-	mode by hitting a key after the "Booting UnixWare..." and
-	the beep. At the prompt
-
-		BOOT#				Hit return only to clear line
-		BOOT# INITSTATE=S
-		BOOT# go
-
-	This will put you into single user mode. Find out ip address,
-	default router and DNS server. At the shell prompt
-
-		# /usr/local/bin/tcsh
-		# setenv TERM vt100
-		# cd /etc
-		# vi resolv.conf
-		< edit and save with :x! >
-		# cd /etc/inet
-		# vi hosts
-		< edit and save with :x! >
-		# vi config
-		< edit and save with :x! >
-		# cd /
-		# shutdown now
-
-	Now it should be possible to restart in single user mode.
-	It may still have long timeouts because the NIS information
-	is wrong. As root you do
-
-		# ypinit -c
-
-	and type in "arda" as NIS domain and "gandalf.du.uab.ericsson.se"
-	as NIS server.
-
-     *	Prebuilding the release. Create a view with the -ncaexported option.
-	See "http://otp/product/internal/test/doc/howto/export_view.html".
-	Build a solaris release (optionally using a boostrap compiler)
-
-		# cd /clearcase/otp/erts/autoconf; cm -V; cd ..
-		# cm -V opt EMULATOR=jam BUILD_ALL=1 >& LOG.1
-
-     *	Create the directories for mount points and mount the view on
-	the UnixWare machine.
-
-		# mkdir -p /clearcase/otp; cd /clearcase/otp
-		# mkdir erts internal_tools libraries system tools
-
-	Use s script like
-
-	    #!/bin/sh
-	    HOST=$1
-	    VIEW=$2
-	    MOUNT=$HOST:/view/$VIEW/clearcase/otp
-
-	    mount -F nfs $MOUNT/erts           $DIR/erts
-	    mount -F nfs $MOUNT/libraries      $DIR/libraries
-	    mount -F nfs $MOUNT/tools          $DIR/tools
-	    mount -F nfs $MOUNT/internal_tools $DIR/internal_tools
-	    mount -F nfs $MOUNT/system         $DIR/system
-
-	to mount the ClearCase VOBs.
-
-     *	Building the 
-     *	Building the 
-	
-	"/usr/X/lib" to your LD_LIBRARY_PATH.
-
-	Had to patch the file
-
-	/usr/local/lib/g++-include/_G_config.h
-
-	not to define _G_HAVE_SYS_CDEFS 1
-
-	Problems with pxw yacc
-
-		yacc -dv -b i386-univel-sysv4.2MP/y parse.y
-		UX:yacc: ERROR: Illegal option -- b
-		UX:yacc: TO FIX: Usage: yacc [-wvVdlt] [-Q(y/n)] [-p driver_file] file
-		gmake[6]: *** [i386-univel-sysv4.2MP/y.tab.c] Error 1
-
-	Create some symbolic links (until got compiled libs for UnixWare)
-
-		# cd crypt/src/ssleay
-		# ln -s elibcrypto.so.i386-pc-solaris2.5.1 elibcrypto.so.i386-univel-sysv4.2MP
-		# cd ssl/src/ssleay
-		# ln -s i386-pc-solaris2.5.1 i386-univel-sysv4.2MP
-
-	Run 
-
-		# ntpdate super.du.uab.ericsson.se
-
-	now and then to set the time on the machine.
-
-
-	Disabled HAVE_MULTICAST_SUPPORT from "drv/inet_drv.c", should be set in configure
-
-	UnixWare want two arguments to 'ln'
-
-	SkunkWare gcc, ln, tar, ..... required, make sure PATH points out them first
-
-	The emulator has to be linked with "gcc -r -Wl,-Bexport " to be linkable
-	with dynamic libraries.
-
-	Tcl/Tk was compiled from
-
-	        tcl7.6p2plus.tar.gz 
-	        tk4.2p2plus.tar.gz
-
-	and the make-files where changed, see
-
-		(not needed it seems, if not using gcc at least)		
-
-
-	VILL HA "-ly -ll" BARA PA PXW  ???????
-
-	You can view the limits of the Unix processes in
-
-		/etc/conf/mtune.d/proc
-
