Problem Description: 

	All known patches to libc for 4.1.1 have been rolled into this 
	one libc set.  The patch id of this patch will remain constant 
	for the life of libc patches for 4.1.1.  Subsequent libc patches 
	will simply be higher revisions of this patch.

	The "standard" SunOS combinations of static, dynamic, and profiled
	libc's are contained in this patch.  In addition, a complete 
	replacement for /usr/lib/shlib.etc has also been included.


INSTALL: 

	The parts list for this patch is listed below.  The list is identical 
	between sun3 and sun4 sets (with the noted exception of the 
	major.minor numbers for the shared libs being different between sun3 
	and sun4).

		lib/libc.a
		lib/libc_p.a
		lib/libc.sa.1.6
		lib/libc.so.1.6
		5lib/libc.a
		5lib/libc_p.a
		5lib/libc.sa.2.6
		5lib/libc.so.2.6
		lib/shlib.etc/lorder-sparc
		lib/shlib.etc/objsort
		lib/shlib.etc/Makefile
		lib/shlib.etc/README
		lib/shlib.etc/awkfile
		lib/shlib.etc/libc_pic.a
		lib/shlib.etc/libcs5_pic.a


The libraries in this patch may be placed in any directory.  But if you
choose to place any libc.* in a location other than /usr/lib or
/usr/5lib, you'll have to use the -L flag with each ld execution to
"point" to the chosen directory that holds these substitutes.  Since
this is likely to be a somewhat awkward requirement, the patch and the
following install sequence assume you wish to substitute your standard
libraries with the patched versions.

The installation of ANY of the library parts may be done while the
system is running, EXCEPT for the SHARED libc's.  It is SAFEST to
substitute the shared libraries while SunOS is booted in single-user
mode or from the SunOS Installation miniroot.  Since using SunOS in
single-user mode is easier than booting the miniroot off the SunOS
Installation tapes, the install sequence below will reference
single-user mode.

There is one more consideration.  The installation sequence below will
overwrite ALL libc "variants" in /usr/lib and /usr/5lib.  If you have
added/substituted parts to libc.a or libc.s?.X.Y in /usr/lib and/or
/usr/5lib, you will need to 1) preserve these copies, or 2) plan to
resubstitute your material in with these patch versions.

It is highly recommended that you "walkthru" the installation sequence
below to become familiar with what is being done prior to actually
doing it.  You can vary and even skip some steps in these instructions
if you're *confident* you understand what is going on.  Bear in mind that
/usr/lib/libc.so.X.Y dynamically binds the *entire* SunOS and any
corruption to this particular library will render a system virtually
useless.


Installing the libc patch:  (perform the following steps in this order)

	o save patch distribution under some directory, say '/tmp/X'.
	o cd /tmp/X
	o su
	o (ensure no users are actively using any libc's)
	o mv /usr/lib/libc.a /usr/lib/libc.a.FCS
	o mv /usr/lib/libc_p.a /usr/lib/libc_p.a.FCS	(1)
	o mv /usr/5lib/libc.a /usr/5lib/libc.a.FCS	(2)
	o mv /usr/5lib/libc_p.a /usr/5lib/libc_p.a.FCS	(2)

	(1) if you do not have this file on your system, then the
	"Debugging" part of the OS distribution tape has not been 	
	loaded.

	(2) if you do not have this file on your system, then the
	"SystemV" part of the OS distribution tape has not been 	
	loaded.

You will rename your original shared libc's at a later point in the
installation.

        o mv /usr/lib/shlib.etc /usr/lib/shlib.etc.FCS
        o mkdir /usr/lib/shlib.etc
        o chmod g+s /usr/lib/shlib.etc

These last 3 steps may be done if you wish to preserve completely your
original /usr/lib/ shlib.etc.  If not, you may skip them.

	o cp -p -R `arch`/* /usr

		The arch command returns either sun3 or sun4. So you are 
		actually copying all the files in the respective directory
		to /usr. If you followed all steps mentioned above you are
		still in /tmp/X.

        o "quiet" system  (have users log off,announce system going down,...)
        o sync
        o halt
        o &gt;b[oot] vmunix -s

You're now booting SunOS in single-user mode.  We will rename the shared
libc's to make them "active" and this is best done, at minimum, under
single-user.

	o cd /usr/lib
	o ls -l libc.s*

		You will get an output similar to the following:

		-rw-r--r--  1 root         7996 Feb  8  1990 libc.sa.1.5
		-rwxr-xr-x  1 root       516096 Feb  8  1990 libc.so.1.5
		-rw-r--r--  1 root         7996 Oct  4 05:00 libc.sa16
		-rw-r--r--  1 root       516096 Oct  4 05:13 libc.so16
	
		In the following move commands you have to substitute the
		X, Y and Z with the numbers you get from your output 
		( from the output above X=1, Y=5, Z=6). 

	o sync
	o mv libc.so.X.Y libc.so.X.Y.FCS     this saves the original file

	o mv libc.soXZ libc.so.X.Z 	     this copies the patch to its 
					     new place
	o mv libc.sa.X.Y libc.sa.X.Y.FCS     this saves the original file

	o mv libc.saXZ libc.sa.X.Z	     this copies the patch to its 
					     new place

	o date

Do this last step CAREFULLY.  IF the 'date' command does *anything*
else but show a proper date, then IMMEDIATELY do:

	o mv libc.so.X.Z libc.soXZ
	o mv libc.so.X.Y.FCS libc.so.X.Y
	o mv libc.sa.X.Z libc.saXZ
	o mv libc.sa.X.Y.FCS libc.sa.X.Y

If the date command is successful, continue here:

	o cd ../5lib
	o ls -l libc.s*

		You will get an output similar to the following:

		-rw-r--r--  1 root         7996 Feb  8  1990 libc.sa.2.5
		-rwxr-xr-x  1 root       516096 Feb  8  1990 libc.so.2.5
		-rw-r--r--  1 root         7996 Oct  4 05:00 libc.sa26
		-rw-r--r--  1 root       524288 Oct  4 05:15 libc.so26

		In the following move commands you have to substitute the
		X , Y and Z with the numbers you get from your output
		( from the output above X=2, Y=5, Z=6).  


	o mv libc.so.X.Y libc.so.X.Y.FCS     this saves the original file

	o mv libc.soXZ libc.so.X.Z 	     this copies the patch to its 
					     new place

	o mv libc.sa.X.Y libc.sa.X.Y.FCS     this saves the original file

        o mv libc.saXZ libc.sa.X.Z	     this copies the patch to its 
					     new place


Do this last step CAREFULLY also.

The 'X' and 'Y' values above correspond to the major/minor revision
numbers of the shared libc's.  These numbers differ between /usr/lib
and /usr/5lib and between sun3 and sun4 versions.

	o ranlib -t /usr/lib/libc*
	o ranlib -t /usr/5lib/libc*

		In these two ranlib commands you will see 
		
			not an archive: ........

		error message for all the libc.so* files. You can
		disregard them. It saves a lot of typing when you
		supply the "*" wildcard instead of typing in the ".a"
		and ".sa." filenames.

	o ^D

The install is complete.  The ^D above terminates single-user mode, and
brings your system back up in multi-user mode.
