Furthemore, these log entries seem to be courtesy of the session init
itself (so, the output of upstart) and running init with -q does not
suppress the messages. So yeah, this is an upstart bug after all.
** Package changed: ubuntu-touch-session (Ubuntu) => upstart (Ubuntu)

Title:
upstart on nexus4 is frequently writing :sys:power_supply-device-
changed event messages
Status in “upstart” package in Ubuntu:
Triaged
Bug description:
Running fatrace on today's ubuntu touch images on the nexus4 I'm
seeing very frequent upstart messages in /var/log/upstart/ubuntu-
touch-session-phablet.log
To reproduce:
sudo apt-get install fatrace
cd /
fatrace -c
init(1): W /var/log/upstart/ubuntu-touch-session-phablet.log
init(1): W /var/log/upstart/ubuntu-touch-session-phablet.log
init(1): W /var/log/upstart/ubuntu-touch-session-phablet.log
init(1): W /var/log/upstart/ubuntu-touch-session-phablet.log
..every second or so an new message is written on an idle phone.
And tail -f /var/log/upstart/ubuntu-touch-session-phablet.log shows:
event_finished: Finished :sys:cpu-device-offline event
event_new: Pending :sys:power_supply-device-changed event
