This happened while copying data over to a new disk (mounted on /mnt
and /mnt/usr; the original disk has only one partition).  The machine
was in single-user mode, but / was mounted read-write due to restore's
insistance on placing temporary files in /tmp (I found out later that
it respects TMPDIR, though the man page doesn't mention it).

root@dsa /mnt# dump -0Laf- / | restore -rf-
  DUMP: Date of this level 0 dump: Thu Jan  9 16:11:42 2003
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping snapshot of /dev/da0a (/) to standard output
  DUMP: mapping (Pass I) [regular files]
  DUMP: mapping (Pass II) [directories]
  DUMP: estimated 1838856 tape blocks.
  DUMP: dumping (Pass III) [directories]
  DUMP: dumping (Pass IV) [regular files]
warning: ./usr: File exists
expected next file 4, got 3
[...]

I can imagine that the file that caused the warning message was one of
restore's temporary files, but a) I've never seen this before, and b)
isn't -L supposed to prevent just that?
