[Tim Waugh <twaugh@xxxxxxxxxx>] directory mounted with --bind causes cp -R to fail

The original appears to have been delayed or lost --
maybe by the list-management software -- so I'm resending this.

  Subject: directory mounted with --bind causes cp -R to fail
  Message-ID: <20030331131708.GH5492@xxxxxxxxxx>

  Original bug report at:
  https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=86302

  Under Linux it is possible to have a special 'bind' mount type, which
  has the effect of remounting part of the file hierarchy somewhere
  else.  But this confuses 'cp --preserve=links':

  Run these commands as root:
    mkdir -p src/{x,y}
    mount --bind src/x src/y
    cp --archive --one-file-system src dst

  Is this a cp bug, or expected behaviour?

  Tim.
