Misc: lifemngr-daemon-on-UOS For cross-VM S5 notify via vUART, life_mngr service is running on UOS. It is listening on /dev/ttyS1 to get SOS's commands. The protocol is: SOS send "shutdown", UOS feedback "acked". When SOS triggle shutdown, SOS can 1) check VM's status until UOS stopped, 2) retry shutdown UOS normally with timeout. So, no matter life_mngr server is running, SOS's shutdown procedure will properly finish.
