[Launchpad Bug Tracker]

This bug was fixed in the package rust-coreutils - 0.7.0-0ubuntu1

---------------
rust-coreutils (0.7.0-0ubuntu1) resolute; urgency=medium

  * New upstream version 0.7.0 (LP: #2143711)
  * Fixes:
    - `man 1 test` is badly formated (LP: #2115782)
    - cp -r /dev/urandom copies content (LP: #2125263)
    - date: gnu date allows options after format (LP: #2142588)
    - autopkgtest failures in resolute due to readlink (LP: #2141441)
  * Refresh patches:
    - Tweak-release-build-profile.patch
    - dd-ensure-full-writes.patch
    - require-utilities-to-be-invoked-using-matching-path.patch
    - use-l10n-translations-in-makefile.patch
    - workspace-exclude.patch
  * Drop patches:
    - prevent-stty-termios2-on-ppc64el.patch: Fixed upstream.
  * Add patches:
    - use-u32-for-ppc64le.patch: Fix type assumption for ppc64 little-endian.
      This relates to the previous dropped patch about termios2, but upstream
      did not treat little- and big-endian ppc64 differently.

Bug description:
  The GNU cp command copies character devices as is if -r is specified:

  ```
  # ls -l /dev/urandom
  crw-rw-rw- 1 root root 1, 9 May  2 08:49 /dev/urandom
  # gnucp -r /dev/urandom foo
  # ls -l foo
  crw-rw-r-- 1 root root 1, 9 Sep 20 15:38 foo
  ```

  The uutils cp command tries to copy the content.
