Title:
  ANACRON_RUN_ON_BATTERY_POWER setting does not work

Status in “anacron” package in Ubuntu:
  New

Bug description:
  Configuration of ANACRON_RUN_ON_BATTERY_POWER does not work on
  Ubuntu(upstart native job) environment.

  /usr/share/doc/anacron/README.Debian said:

    "By default, anacron does not run while on battery power.  See
  /etc/default/anacron to change that."

  And, default /etc/default/anacron are:
  ---------------------------------------------------
  # If set to "yes", start anacron even when on battery power.  By
  # default, the /etc/init.d/anacron script tries to avoid running
  # anacron unless on AC power, so as to avoid running down the battery.
  # (Things like the locate updatedb cause a lot of I/O.)

  ANACRON_RUN_ON_BATTERY_POWER=no
  ---------------------------------------------------

  But this feature does not work at all, because
  ANACRON_RUN_ON_BATTERY_POWER are implemented  by sysv init
  scripts(debian/init.d).

  debian/init.d has below, but /etc/init/anacron.conf did not care it.
  --------------------------------------------------------
      if test x"$ANACRON_RUN_ON_BATTERY_POWER" != x"yes" && test -x /usr/bin/on_ac_power
      then
          /usr/bin/on_ac_power >/dev/null
          if test $? -eq 1
          then
            log_progress_msg "deferred while on battery power"
            log_end_msg 0
            exit 0
          fi
      fi

      # on_ac_power doesn't exist, on_ac_power returns 0 (ac power being used)
      # or on_ac_power returns 255 (undefined, desktop machine without APM)
      start-stop-daemon --start --exec /usr/sbin/anacron -- -s
