** Changed in: zfs-linux (Ubuntu Xenial)
       Status: New => In Progress

** Description changed:

  [Impact]
  
  The zfs utilities scripts shipped with debian and ubuntu such as :
  
      * arc_summary.py : Provides a summary of the statistics
      * arcstat.py : Print out ZFS ARC Statistics exported via kstat(1)
      * dbufstat.py : Print out statistics for all cached dmu buffers
  
  should be renamed according to Policy 10.4 :
  https://www.debian.org/doc/debian-policy/ch-files.html#s-scripts
  
  "When scripts are installed into a directory in the system PATH, the
  script name should not include an extension such as .sh or .pl that
  denotes the scripting language currently used to implement it."
  
- 
- Ideally, this should be fixed and upstreamed to Debian (or to zfslinux upstream) as well.

  [Test Case]
  
   * Install zfsutils-linux
   * List files
  
   $ dpkg -L zfsutils-linux | egrep "arc|dbufstat"

  [Regression Potential]
  
   * none expected, this is a trivial change that simply rename the
  scripts to remove the extension (.py) with a simple 'mv' before the
