        This revision has been generated to workaround bug 4010430 -- 
        installpatch should ignore a required patch when not applicable 
        to a target system.  The workaround is to include an empty root 
        sparse patch package.  This will allow patch dependency requirement 
        to be met in a server/client configuration.

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:
                		105778-01  /kernel/fs/specfs
                		105780-01  /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:
		106141-01  /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,   
                	105490-04 (or newer).

NOTE 4:  	To get the complete fix for bug 4125102 (ufs_itrunc()/
                 	top_end_async() deadlock) we recommend installation of
                 	106625-06 (or newer revisions) plus the following SDS
	patches:
		SDS4.1 sparc 104172-17
		SDS4.2 sparc 106627-05

NOTE 5: 	To get the complete fix for bug 4232237 (bug in the POSIX
                	Message Queue) we recommend installation of 106797-03
                	(or newer revisions). 

NOTE 6: 	For the users of sun4u/sunfire platform, To get the complete
                	fix for bug 4164648 (Software clock has no prevention for 
                	possible broken tod) we recommend installation of 105651-11
                	(or newer revisions). 

NOTE 7: 	To get the complete fix for bug 4224166 (TPI messages get
                	flushed if 3rd party module processe M_PROTO in service
                	proced) we recommend installation of 105621-22  (or newer
	revisions).
	
NOTE 8: 	For the socket command under crash to display the correct 
	socket flags, we recommend installation of 108794-01 (or 
	newer revisions).

NOTE 9: 	To get the complete fix for bug 4201921 (lwp_create of ts
                	thread causes NULL in suser) we recommend installation of
                	108796-01 (or newer).
	
NOTE 10: 	The fix for bug 4116873 causes wait i/o numbers to be reported
	on a per cpu basis;  this will generally have the effect of
	reducing its magnitude on MP systems.
        
NOTE 11: 	To get the complete fix for bug 4224166 (TPI messages get
                 	flushed if 3rd party module processes M_PROTO in service
                 	proced), bug 4162091 (fork in MT process can hang proces in
                 	sockfs due to cv_wait/cv_wait_sig dependen) or bug 4290575
                 	(2nd connect() to determine status of non-blocking connect
                 	sends extra Syn) we recommend installation of 109417-01 (or newer).
	
NOTE 12: 	To get the complete fix for bug 4253437 (Ansync I/O problem) 
	we recommend installation of 105210-32 (or newer).
