What happens if you have a slightly bad power supply? Does it immediately
go read only all the time? It would definitely need to be able to
recover operations as soon as the power was "normal" again, even if this
caused basically "sync" I/O to the disk. Maybe it would be able to
report this to the user via SMART, I don't know.
Cheers, Andreas
