>Description:
It's not possible to restore a multi volume dump to a tap with restore
because st(4) return EIO instead of 0 bytes read when end of media
is detected.

>How-To-Repeat:
Try to restore a multi volume tar or dump archive on a NetBSD system.

>Fix:
Return 0 bytes read instead of EIO if end of media is found while reading
a tape.
