Patch Installation Instructions:
Please refer to the man pages for instructions on using 'patchadd'
and 'patchrm' commands provided with Solaris.
The following example installs a patch to a standalone machine:
       example# patchadd /var/spool/patch/123456-07
The following example removes a patch from a standalone system:
       example# patchrm 123456-07
For additional examples please see the appropriate man pages. Any
other special or non-generic installation instructions should be
described below as special instructions.

Special Install Instructions:
For the changes in this patch to become effective, a reboot may be performed, or
alternatively, the X Window System font server process, xfs, must be killed if
it is already running.
The X font server, is normally started automatically from inetd on Solaris when
a request for a font service is received.  Xsun clients using the font server
will detect the font server shutdown and reconnect automatically to a new
instance of the font server. Unfortunately, some other font clients, such as
some versions of Xvnc, will not reconnect automatically and will need to be
stopped before killing the font server and restarted again after the font server
is restarted.  (If xfs is still being run from inetd, inetd will automatically
restart on the first connection attempt).
To kill the font server, as root, run the command:
pkill -x xfs
