What do hobbyist normally do to do a graceful shutdown when there's power cuts?
Does a Power Management Unit (PMU) handle this, or is a VDC Uninterruptible Power Supply needed?
With a PMU can you just customize your Linux shutdown, or must you interface with the unit?

Relevant to my interest.

Wuts dat bord?
I have a small UPS that tells my two Rpi 0's to shutdown fully if the power goes out
it gives them both about 10 minutes of power which is plenty to shutdown
All i use them for is a really small home NAS anyway, even if they hard shutdown it would probably be fine
it was like 40$, i originally used it for my comcast cable box because every time the power went out the cable box would die for some reason and comcast is a cunt and charged me for replacements

How can your UPS tell the rpi to shutdown?

So.. What UPS is this and what interface is this signal travelling over ? Did you implement this shtick with some high order software like nc (does this UPS act as a tiny Linux terminal?) Or what ?
