Hello,
I have my computer hooked
up to an AVR that runs my home cinema and ideally I would like the computer
to turn off the AVR when I turn it off or suspend it. The only way to do
this is over network and I wrote a simple script that does just that.
Hooking it to shutdown was quite easy using network.target that is defined
when shutting down.
I am struggling to make it
work with suspend though. When I look at the logs, terminating network
seems to be the first thing that happens when suspend is invoked. I tried
putting the script to /usr/lib/systemd/system-sleep/ and it runs, but only
after network si down, so it fails. Running the script with systemd-inhibit
(ExecStart=/usr/bin/systemd-inhibit
--what=sleep my_script) tells me that "Failed to inhibit: The operation inhibition has
been requested for is already running".
Is
there a way to make this work with service files by specifying that the
script needs to be run before network is shut down or would I need to run a
daemon listening for PrepareForSleep as here: https://github.com/davidn/av/blob/master/av ?
Kind
regards,
Tomas
