Patch Installation Instructions:
--------------------------------
 
For Solaris 2.0-2.6 releases, refer to the Install.info file and/or
the README within the patch for instructions on using the generic
'installpatch' and 'backoutpatch' scripts provided with each patch.
 
For Solaris 7-10 releases, refer to the man pages for instructions
on using 'patchadd' and 'patchrm' scripts provided with Solaris.
Any other special or non-generic installation instructions should be
described below as special instructions.  The following example
installs a patch to a standalone machine:
 
       example# patchadd /var/spool/patch/104945-02
 
The following example removes a patch from a standalone system:
 
       example# patchrm 104945-02
 
For additional examples please see the appropriate man pages.

Special Install Instructions:
-----------------------------
 
NOTE 1:  If you're planning to set up Zones on this system, please make
         sure to install the following patch which fixes bugid 6216195
         (zone installation confused by UPDATE=yes in pkginfo(4) file):
 
         119015-01 (or greater)  Install and Patch Utilities Patch
 
         (Note that 119254 has superseded 119015; installation of the
          current version is recommended to be preferred, due to its
          central role in the installation and removal of patches.)
 
NOTE 2:  Although this patch does not require a reboot of the system, the
         root user who is installing the patch will likely be using the
         shell /sbin/sh or one of its links, such as /usr/bin/sh.  If so,
         the user should first invoke a different shell (e.g., csh, ksh)
         before running patchadd, since this patch will replace the existing
         /sbin/sh.
