For example, I think we've already made good progress towards
standardising the industry around dm-verity.  (At least, I keep
on encountering it being used in various different places, rather
than people attempting to develop their own version.)  We extended
that concept with dm-integrity but I'm less sure about how widely
that has been taken up so far.

For edge systems needing unattended remote reliable updates, our
high-level challenge here is: Can we together develop a decent and
efficient solution for OTA updates that the industry will be happy to
standardise around?
