When toggling the switch, a lock is held for a relatively long time,
preventing another toggling of the switch to be noticed. With this
change, I hope we can first shutdown the modem, wait for a toggle, and
then continue.
We're losing the abort function but I currently don't know how we would
be able to keep that functionality given that the toggle is queued and
we don't get the notification.
I hope that this allows us to use the toggle again to advance the Blue
Merle logic.
If all goes well, the script finishes execution and the switch lock in
/var/lock/gl-switch.lock is released so that the button can be used
again.
We don't want to let it run forever because it blocks the toggle from
working. But even if it's not, we wouldn't want to have the script run
eternally.
I think we can only toggle while the handler is not active.
I toggled to ON and got the script running. But then I couldn't toggle
OFF, presumingly because the script was still running.
By sending it to the background I hope it will allow me to toggle OFF.
I don't know whether this works. On the v4 firmware, we can see files in
/etc/gl-switch.d but I don't know yet how the system determines which
file to choose. I assume it's dependend on the "page" of the display.
But I haven't figured out yet how or rather where those pages are
organised.
