  cp -r /dev/urandom copies content

Status in coreutils-from package in Ubuntu:
  Fix Released
Status in rust-coreutils package in Ubuntu:
  Confirmed

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.
