Patch Installation Instructions: 

-------------------------------- 
Refer to the Install.info file within the patch for instructions on
using the generic 'installpatch' and 'backoutpatch' scripts provided
with each patch.  Any other special or non-generic installation
instructions should be described below.

Special Install Instructions: 

----------------------------- 
Reboot the system after patch installation.

	NOTE 1:  To get the complete fix for bug 4090929 (system panics due to
       	         infinite recursion in prrealvp) we recommend installation of
                 rev 01 (or newer revisions) of the following patches:

                	105779-01  /kernel/fs/specfs
                	105781-01  /kernel/fs/fifofs

	NOTE 2:  To get the complete fix for 1237009 (users umask modifies
                 ACL's of new files under default ACL's) and 4073684 (mkdir
                 -p dir" and "mkdir dir" work differently in the presence
                 of default ACLs), we recommend installation of rev 01
                 (or newer revisions) of the /usr/bin/mkdir patch:

			106142-01  /usr/bin/mkdir

	         As a result of this fix for 1237009, the umask/ACL interaction  
		 has changed.  

                 Please refer to the following paragraph for a revision to the
		 manpage for the command 'setfacl' which defines the new umask/ACL
                 interaction.

                 ************************************************************

                 A directory may contain default ACL entries.  If a  file
                 is created in a directory that contains default ACL entries,
                 the newly created file will have permissions generated
                 according to the intersection of the default ACL entries,
                 and the permissions requested at creation time.

                 The umask(1) will not be applied if the directory contains
                 default ACL entries. If a default ACL is specified for a
                 specific user (or users), the file will have a regular ACL
                 created;  otherwise, only the mode bits will be initialized
                 according to the intersection described above.  The default
                 ACL should be thought of as the maximum discretionary access
                 permissions that may be granted.

                *************************************************************

	NOTE 3: For users running Java or other multithreaded applications.
                We highly recommend installing the linker patch,   
                105491-04 (or newer).

        NOTE 4: To get the complete fix for bug 4232237 (bug in the POSIX 
                Message Queue) we recommend installation of 106798-03
                (or newer revisions).
