yes this is what is happening, both plugging in charger and then
switching off device,
or plugging charger with device already switched off.

Nice question :-). Personally, I would prefer to find device in the
same state I leaved it.
( except for the discharged battery, of course ;-)   )

I see.
Anyway, i removed "/var/lib/dsme/stats/lifeguard_restarts" file,
powerd off the device, and plugged charger in. As usual the device
booted by himself, but the file /var/lib/dsme/stats/lifeguard_restarts
is still absent.
