Arch Linux

This should probably be filed to upstream, but I can't find a bug reporting tool for it...

Description:

Current upower version (0.9.18) ships with a "/usr/lib/systemd/system-sleep/notify-upower.sh" script which, as any script in that dir, gets called by systemd before sleep with "pre" argument and after wakeup with "post" argument.
The script's content is currently as follows...

--- begin script ---
#!/bin/bash
[ "$1" = "post" ] && exec /usr/bin/dbus-send \
--system --type=signal \
--dest=org.freedesktop.UPower \
/org/freedesktop/UPower \
org.freedesktop.UPower.Resuming
--- end script ---

For some reason, when it gets called by systemd before sleep (with "pre" argument), it exits with 1, so systemd produces an error message to the system journal, like this: "systemd-sleep[7909]: /usr/lib/systemd/system-sleep/notify-upower.sh exited with exit status 1."
This gets fixed by changing the script to something like the following.

--- begine script ---
#!/bin/bash
if [ "$1" = "post" ]; then
exec /usr/bin/dbus-send --system --type=signal --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.Resuming
else
exit 0
fi
--- end script ---


Additional info:
* package version(s): extra/upower 0.9.18-2

Steps to reproduce:
put the pc to sleep, resume it, see the system journal
