(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? Gordon L.
