Description degeneloy 2018-02-22 15:27:50 UTC 
Description of problem:
Fwupd is continuously using RAM as a background daemon, while this is not really necessary to run the daemon unless there are updates to be installed.

Version-Release number of selected component (if applicable):
client version:	0.9.7
daemon version:	0.9.7
compile-time dependency versions
	appstream-glib:	0.7.2
	gusb:	0.2.11

Expected results:
It would probably be preferred to use systemd timers to run the fwupdmgr utilities once in a while, to check for updates and install them. 

Additional information:
These utilities automatically start the daemon, so it would be necessary to shutdown the daemon afterwards.
Comment 1 Richard Hughes 2018-02-22 15:58:06 UTC 
How would we do hardware hotplug?
Comment 2 degeneloy 2018-02-22 16:38:38 UTC 
Can a generic udev rule start the daemon at a hotplug event? Or would it need to be running before the hotplug events occurs because it listens to dbus hotplug events?
Comment 3 Richard Hughes 2018-02-22 21:33:09 UTC 
I listens to all kind of hardware, using libusb, gudev and others. This isn't something I really want to discuss on a downstream bugtracker, sorry. If you have an idea please file an upstream issue and we can discuss there.
