Public bug reported:
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
