Symptoms:
	PHCO_11647:
	Same as PHCO_11345.

	PHCO_11345:
	When a (undocumented) kernel parameter hpux_aes_override
	is set to 1 on a system, tlinstall creates some "strange"
	directories (with some unprintable characters as part of
	the directory names).

	This usually happens after using swinstall to install
	any fileset. tlinstall command will run at the end of
	a swinstall (Unless Upgrade.UPG-TLINK has been removed
	fromthe system.) When the hpux_aes_overrride is set to 1,
	such "strange" directories are created.

Defect Description:
	PHCO_11647:
	Same as PHCO_11345.

	PHCO_11345:
	In the application notes of 10.10 and 10.20, the
	manpages warn about using readlink(2): "portable
	applications should not assume that the returned
	contents of the symbolic link are null terminated."

	tlinstall assumed all the pathnames returned by
	readlink(2) were null terminated. As a result, some
	strange directories pathnames were created after
	running tlinstall.

Installation Instructions:

	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHCO_11647

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHCO_11647.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHCO_11647.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHCO_11647.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHCO_11647.text file to
	/var/adm/sw/patch for future reference.

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHCO_11647.depot of=/dev/rmt/0m bs=2k
