Title:
  "tail -f file" with "mv file file2" does not show changes to file2

Status in coreutils package in Ubuntu:
  Confirmed

Bug description:
  The manual page of tail states the following:

    With  --follow  (-f),  tail  defaults to following the file descriptor,
    which means that even if a tail'ed file is renamed, tail will  continue
    to  track  its  end.

  However, the following command sequence does not behave like that:

  touch file
  tail -f file &
  mv file file2
  echo "text" >> file2

  In this case, tail does not show any output. However, tail shows the
  "text" properly when run on a Solaris server. This indicates that tail
  does behave like its manual page states in some versions.

  
  System version: Ubuntu 12.04.2 LTS
  touch version: touch (GNU coreutils) 8.13
  tail version: tail (GNU coreutils) 8.13
  mv version: mv (GNU coreutils) 8.13
  bash version: GNU bash, version 4.2.24(1)-release (x86_64-pc-linux-gnu)

  
  On the Solaris server that behaves correctly, each are '(GNU coreutils) 6.7' except bash which is 'GNU bash, version 3.2.25(1)-release (sparc-sun-solaris2.11)'
