Description selurvedu 2018-05-07 23:57:25 UTC
$ cat /etc/cron.daily/mlocate
#! /bin/sh
set -e

# check if we run on battery and if so then don't run
if which on_ac_power >/dev/null 2>&1; then
	on_ac_power >/dev/null 2>&1 || ON_BATTERY=$?
	if [ "${ON_BATTERY}" -eq 1 ]; then
			exit 0


My system did not have the on_ac_power script installed, so the above cron script was unable to detect whether the laptop is running on battery (`which` never succeeded, so no checks were performed).

I think that the sys-apps/mlocate ebuild should either write a post-install message about an optional dependency to let the user decide whether he needs that kind of check, or there should be a corresponding USE flag.
