Removing the sgi bug system from the cc list here......
The interesting case is being able to restore into xfs from a dump taken
on a different filesystem type. You could argue that doing it the other
way and dropping all the xfs special attributes on the floor is also a
reasonable thing to do. This would not be useful for doing backups of
XFS filesystems, but for moving data between xfs and non-xfs filesystems -
but then tar does about the same thing, so maybe this is a moot point.
Unfortunately, the individual who was pushing hard for this has long since
left the company - along with the details of his reasoning on this.....
