Title:
  (Vivid) zram-config 0.3 Job for zram-config.service failed

Status in linux package in Ubuntu:
  Incomplete
Status in zram-config package in Ubuntu:
  Fix Released
Status in linux source package in Vivid:
  Incomplete
Status in zram-config source package in Vivid:
  Fix Committed

Bug description:
  [Impact]
   * People using some non English locale, zram devices are not loaded
   * The service fails to stop and unloading zram module as well

  //who wrote this? The impact is probably for all languages including English. The new version works : provided zram module is blacklisted to avoid being loaded during boot! See my next comment which will be #13. 
  Thanks, Mélodie

  [Test Case]
   * Install the new zram-config package
   * Reboot and check that the zram devices are created:
  $ swapon -s
  -> returns some zram devices
   * $ sudo systemctl status -l zram-config.service
  -> no error
   * Stop the service:
  $ sudo systemctl stop zram-config.service
   * $ sudo systemctl status -l zram-config.service
  -> no error
   * swapon -s
  -> no more zram device listed

  [Regression Potential]
   * Services loading change may impact English-local user. However, the fix has already been confirmed to be working on wily.
   * Stopping the service was already failing on unloading the module, so no additional regression is possible there.

  --------------------
  Hi,

  While testing how zram-config is going in Ubuntu Vivid, I meet with
  error while doing restart and or stop/start.

  It seems to stop fine but throws an error when starting again or
  performing a restart.

  I have installed zram-config 0.3 just today and haven't rebooted yet.
  The CPU is "AMD Athlon(tm) II X2 260 Processor"

  As stated in bug #1449665 there is one block device created:

  $ cat /proc/swaps
  Filename				Type		Size	Used	Priority
  /dev/zram0                              partition	947216	0	5
  $

  Here:
  $ sudo systemctl stop zram-config
  $ cat /proc/swaps
  Filename				Type		Size	Used	Priority
  /dev/zram0                              partition	947216	0	5
  $

  after the stop, the prompt is back without error, but it has done
  nothing.

  With restart:
  $ sudo systemctl restart zram-config
  Job for zram-config.service failed. See "systemctl status zram-config.service" and "journalctl -xe" for details.
  $

  When invoking the suggested commands:

  I have done a test using directly the scripts created for /usr/bin,
  the results seem interesting:

  $ sudo /usr/bin/end-zram-swapping
  rmmod: ERROR: unexpected getopt_long() value 'w'.
  $ cat /proc/swaps
  Filename				Type		Size	Used	Priority
  $

  $ LANG=C sudo /usr/bin/init-zram-swapping
  sh: echo: I/O error
  mkswap: error: /dev/zram0 is mounted; will not make swapspace
  swapon: /dev/zram0: swapon failed: Device or resource busy
  /usr/bin/init-zram-swapping: 21: /usr/bin/init-zram-swapping: cannot create /sys/block/zram1/disksize: Directory nonexistent
  /dev/zram1: No such file or directory
  swapon: stat failed /dev/zram1: No such file or directory
  $

  I hope I have tested the right way. If anything more is needed, log
  files or so, please ask.

  Best regards,
  Mélodie
