1136478  The library libC.so.4 will be bundled with SunOS 5.4 but is
         not bundled with SunOS 5.2 and "end-user" cluster of SunOS 5.3.
         (This library is bundled with "all" cluster of SunOS 5.3).
         This patch is meant for users of SunOS 5.2 and users who have
         installed the "end-user" cluster of SunOS 5.3.


Patch Installation Instructions: 
-------------------------------- 
The command 'pkgadd' should be used for installing this patch and
'pkgrm' should be used to remove this patch.

Special Install Instructions: 
----------------------------- 
   This patch should be installed on the workstation of each user
   who needs /usr/lib/libC.so.5. Simply installing this patch on a 
   server will not help.


Instructions to install patch
-----------------------------

1.  Become super-user.

2. Remove the existing SUNWlibC package if it exists on your machine by
   typing the command:

        pkgrm SUNWlibC

3.  Apply the patch by typing:

	pkgadd -d <dir>/<patch-id> SUNWlibC

    where <dir> is the directory containing the patch and <patch-id>
    is the patch number.  <dir> must be a full path name.

    Example:

	# pkgadd -d /tmp/123456-01 SUNWlibC


Instructions for installing a patch on a diskless or dataless client
--------------------------------------------------------------------

1.  Before applying the patch, the following command must be executed
    on the server to give the client read-only, root access to the
    exported /usr file system so that the client can execute the
    pkgadd command:

    share -F nfs -o ro,anon=0 /export/exec/Solaris_2.1_sparc.all/usr

    The command:

    share -F nfs -o ro,root=<client_name> \
		/export/exec/Solaris_2.1_sparc.all/usr

    accomplishes the same goal, but only gives root access to the
    client specified in the command.

2.  Login to the client system and become super-user.

3.  Continue with step 2 in the "Instructions to install patch using
    installpatch" section above.


Instructions for backing out patch using "backoutpatch"
-------------------------------------------------------

1.  Become super-user. 

2.  Backout patch by typing:
 
        pkgrm SUNWlibC
