Patch Installation Instructions:
--------------------------------
Refer to the man pages for instructions on using 'patchadd' and 'patchrm'
scripts provided with Trusted Solaris. Any other special or non-generic
installation instructions should be described below as special instructions.
 
For additional examples please see the appropriate man pages.

Special Install Instructions:
-----------------------------
NOTE 1:	Reboot the system after the patches are removed.
 
NOTE 2: To obtain the complete fix for 5044793 one must install 
        the following patch:
 
	117491-02 (or newer)	genunix_policy patch
 
The steps below assume the patch has been put into an ADMIN_LOW
directory in /var/tmp and the patch file label is configured to ADMIN_LOW.
 
Create a role which contains the Software Installation profile
(typically admin role is assigned this profile) and whose label
range includes the ADMIN_LOW label.  All the steps in the patch
installation should be executed at ADMIN_LOW.
 
The patch should be owned by this role.
 
        1) Login as a user authorized to assume a role that contains the
        Software Installation profile; typically the admin role.
        Assume that role.
 
        To verify the profile is assigned to the role, type:
        "profiles -l | grep patchadd".
 
        The result should be:
         /usr/sbin/patchadd    uid=0, privs=all, label=admin_low
 
        2) cd into /var/tmp and install the patch file.
 
        # cd /var/tmp
        # patchadd /var/tmp/<patch-id>
 
        where <patch-id> is the patch number.
 
Special Backout Instructions:
-----------------------------
NOTE 1:	Reboot the system after the patches are installed.
 
        1) Login as a user authorized to assume a role that contains the
        Software Installation profile; typically the admin role.
        Assume that role.
 
        To verify the profile is assigned to the role, type:
        "profiles -l | grep patchrm".
 
        The result should be:
        /usr/sbin/patchrm    uid=0, privs=all, label=admin_low
 
        2) Backout patch by typing:
 
        # patchrm <patch-id>
 
        where <patch-id> is the patch number.
