Guys, please don't argue on kindergarten level. The UPS is for backing a
sudden death, but not for running five days. Of course you can do a controlled
shutdown if battery level falls below a trigger value. And this is about all
you need: control. There is no fs error as long as you perform a regular
shutdown. If UPS-backup is forbidden in your country then I suggest moving to
civilized regions of the planet ;-)
