Bug description:
  I've had a number of deployment faults where curtin would report
  Timeout exceeded for removal of /sys/fs/bcache/xxx when doing a mass-
  deployment of 30+ nodes. Upon retrying the node would usually deploy
  fine. Experimentally I've set the timeout ridiculously high, and it
  seems I'm getting no faults with this. I'm wondering if the timeout
  for removal is set too tight, or might need to be made configurable.
