>Description:

Running the ATF tests now causes a lot of LFS releated error messages
to be logged, for example:

      lfs_extendfile: Aug 23 15:18:40  lfs_cleanerd[22597]: couldn't convert '/dev/device0.lfs' ro raw name: No such file or directory
  Aug 23 15:18:40	 lfs_cleanerd[22597]: /mnt: couldn't init: error code -1
  [4.201046s] Passed.
      lfs_extendfile_append: Aug 23 15:18:44  lfs_cleanerd[20748]: couldn't convert '/dev/device0.lfs' ro raw name: No such file or directory
  Aug 23 15:18:44	 lfs_cleanerd[20748]: /mnt: couldn't init: error code -1
  [4.022019s] Passed.
      lfs_holywrite: Aug 23 15:18:48  lfs_cleanerd[21480]: couldn't convert '/dev/device0.lfs' ro raw name: No such file or directory
  Aug 23 15:18:48	 lfs_cleanerd[21480]: /mnt: couldn't init: error code -1
  [3.524514s] Passed.

This started with the following commits:

  2019.08.22.20.23.43 brad src/lib/libutil/getdiskrawname.c 1.6
  2019.08.22.20.26.07 brad src/sbin/resize_lfs/resize_lfs.c 1.15
  2019.08.22.20.28.08 brad src/libexec/lfs_cleanerd/lfs_cleanerd.c 1.59

The tests are passing despite the error messages.

Also, I'm guessing the "ro" should be "to".

>How-To-Repeat:

Run the ATF tests.
