# cloud-init applies user-data once per INSTANCE, not once per boot: rewrite
# user-data on a card that has already booted and nothing happens, because
# cloud-init recognises the instance id and skips straight to per-boot modules.
#
# Deriving the id from a hash of user-data itself fixes that. Re-running
# `make bootfs` with no changes leaves the id alone, so a card keeps its
# identity; change anything in user-data and the id changes with it, and the
# Pi re-applies the new config on its next boot without a reflash.
