o Add a comment indicating that if /tmp==/var/tmp in rc.diskless2, the

  md device and file system creation occurs *after* mtree is run, and
  as such an /var/tmp/* or /tmp/* entries will be under the mountpoint
  (or fail) rather than appearing in the md filesystems.  This prevents
  the creation of vi.recover, and might affect other localizations that
  rely on the mtree calls affecting these directories.
