# This expects the device to be in zedboot mode, with a zedboot that is
# is compatible with the Fuchsia system image provided.
#
# The first and only parameter should be the path to the Fuchsia system image

# This script expects `pm`, `device-finder`, and `fuchsia_ctl` to all be in the
# same directory as the script.
#
# This script also expects a private key available at:
# "/etc/botanist/keys/id_rsa_infra".
