>Description:
	
	Dumps made on 5.0-RELEASE are unrecognizable as dumps on
	4.7-RELEASE (even a dump of a UFS1 root filesystem with no
	softupdates).
>How-To-Repeat:
	
	Dump the root filesystem on a 5.0-RELEASE machine.
	(I am not sure whether use of -L matters or not.  I did use it.)
	Move it to a 4.7-RELEASE machine and try to extract into
	a temporary directory or just try to list it.
>Fix:

	
	This change is serious enough to warrant putting in the release
	notes, and as near as I can tell, this wasn't done (CURRENT
	is bleeding-edge, but I'm using FreeBSD 5.0-RELEASE).  I also
	note in the source to "restore" that support for reading "old" UFS
	dumps is being dropped; that ALSO should be in release notes.
	(When was "old" UFS replaced?  1995?  It still affects archives
	of people's old dumps).

	I think some additional data relating to dump/restore should
	be put into the documentation.  What is dumped and restored
	on a UFS2 file system?  (in particular, does this include
	extended attributes, MAC labels, ACLs, snapshots, file birth
	time, etc.?  What else is there in a UFS2 filesystem not
	in a UFS1 filesystem that I didn't list?)  If you attempt
	to restore a UFS2 dump to a UFS1 filesystem, does it work?
	Do you get back everything representable on a UFS1 filesystem?
	
	Is there any reason not to make *UFS1* filesystem dumps readable
	by older versions of restore?

 I also noted that I could not restore dumps of a ext3 or ext2 partition
 made on a linux machine on 5.0R. Same dumps got restored by 4.7STABLE
 quite fine.
 
 I think I could not even restore dump done on 4.7STABLE on the 5.0R
 machine.

Closing this ticket, sadly we didn't pick this up earlier 
so that we could resolve it, but currently we are no longer 
supporting 4.x at all. Thanks for the submission though!
