[lug] Confused about what cp -x does

[Evelyn Mitchell]

The info page for cp is more complete than the man page:

  `-x'
  `--one-file-system'
       Skip subdirectories that are on different filesystems from the one
       that the copy started on.  However, mount point directories
       _are_ copied.
