		DFU 2.4 Eco 2 Release Notes
		===========================

		To : All DFU subscribers


	1. Introduction
	---------------

	Several problems have been discovered for V2.4 of DFU.
	Part of these were already covered by ECO1. This
	new ECO2 kit solves some additional problems.
	
	This ECO kit is now available as :

  	  UTRTSC::SYS$PUBLIC:DEC-AXPVMS-DFU-V0204-2-1.PCSI;1 (Alpha)
	  UTRTSC::SYS$PUBLIC:DEC-VAXVMS-DFU-V0204-2-1.PCSI;1 (VAX)

	This kit will bump up the I2.4 version of DFU
	to I2.4-2.

	Installation of this kit is recommended if you are
	using the VERIFY/DIR and/or the DELETE/DIR command.
	See .5 for a description of all the fixes.

	2. Before you install ECO 2.
	----------------------------

	Before you install this ECO kit you must check
	the following :

	- Installation is done via the PRODUCT INSTALL
	  command. This means that this ECO kit con only be installed
	  on VMS V6.1 and higher (up to and inluding VMS 7.1).

	- If DFU is INSTALLed (via DFU$STARTUP) you must manually
	  remove DFU via the following command:

		$ INSTAL REMOVE SYS$SYSTEM:DFU
	
	  Failing to do so will result in problems during
	  installation.

	- This kit is INTERNAL USE ONLY. Do not install
	  this kit outside Digital EASYNET. 


	3. Installation procedure. 
	--------------------------

	After copying the kit to your own directory
	installation is performed via the following command :

	$ PRODUCT INSTALL DFU/SOURCE=<disk>:[your_directory]

	During the installation you will have the option
	of installing the documentation.

	This kit is a full installation kit and can also be
	installed even if DFU has not been installed before.


	4. Restrictions and support
	---------------------------

	This version DFU is strictly INTERNAL USE ONLY. 
        Apart for this release notes I have not changed
	the original V2.4 documentation. Also the help
	file is unchanged.
	
	The installation procedure no longer offers the possibility
	to install to a private directory. Instead a new file
	SYS$SYSTEM:DFU.EXE is created; you may want to move the
	file from there to your own directory.

	Support as always is not official, but I appreciate
	any problems reported to me at UTRTSC::DORLAND
	or [email protected].
	You may also post replies to note 1533 at NOTED::HACKERS.

	I will try to fix any serious problems found with DFU.
	

	5. Problems fixed in ECO 2
	--------------------------

		Fix for DELETE/DIRECTORY :

	- The DELETE/DIRECTORY code has been rewritten. Previously
	  files which couldn't be deleted for some reason became 'lost'
	  files. As of V2.4 non-privileged users can use this command 
	  so this has become a major problem. As of ECO 2 such files
	  will now be left intact in their original directory.
 
		Fix for VERIFY/DIRECTORY :

	- Yet another problem was discovered which could cause
	  a valid directory to be 'seen' as invalid. As a result
	  all files within this directory would be marked as lost
	  files. This problem could only occur under very rare 
	  circumstances.

		Fixes for DEFRAG/DISK :

	- Several minor problems were fixed. These fixes will
	  result in better defragmentation.



	Problems fixed in ECO 1
	--------------------------

		General fixes:

	- Previous versions of DFU always required an exact device
	  name (or a logical name). As of ECO 1 DFU allows some more
	  freedom, eg. if the device is named $1$DIA1 DFU will now
	  also accept DIA1, or even DIA if there is only one DIA
	  device. If the device name is not unique DFU will
	  display the new error message : 

		%DFU-E-NOTUNIQ, Device name is not unique
	
	- Some DFU commands flushed the disks ACP caches when it
	  was not really necessary


		Fixes for VERIFY/DIR:

	- The VERIFY/DIR/FIX command could result in a computable
	  loop
	- VERIFY/DIR and some other commands could result in
	  an ACCVIO if the directory was not named .DIR;1
	- Sometimes VERIFY/DIR would report a directory as invalid.
	  This could only happen if the first directory entry
	  in a block was exactly 256 bytes large.
	- Files with 'lost' backlinks are now correctly reeentered
	  in the original directory 


		Fixes for SEARCH:

	- SEARCH/FULL did not properly display the file date fields.
	  An ASCII date field is 23 bytes, but DFU only displayed
	  21 or 22 bytes.
	- Fixed a rare problem where SEARCH resulted in files with
	  '[]' as the resultant directory. This could only happen
	  when BYPASS privilege was disabled. Also DEFRAGMENT/LBN
	  sometimes gave a NOVOLSET error; this problem was caused 
          by the same bug.
	- SEARCH /FORMAT /APPEND did not work due to a bug in
	  the command definition file.

    	Rgds, Ton

A customer is chaning the UICs of all their users, and there are files with ACLs 
containing those UICs all over the place.

Can I use DFU to find files that have ACEs containing a specific UIC, and change 
that UIC to something else?

PJDM

    Sorry for replying this late but I was not at the office last week.
    Anyway, DFU has no option to SEARCH for specific ACE's so the
    answer is that you can't do that with DFU.
