For Solaris 7 release, 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: ----------------------------- The X Window System Font Server, xfs, is normally started automatically from inetd on Solaris when a request for a font service is received. Therefore, to protect a running system against bug 4764193, after installing this patch, you must either reboot or stop all running xfs instances. 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 xfs, use ps to identify the process id of 'fs' and, as root, run 'kill '.
