With --reboot, a restore of the radio alone brings it back as it was:
on a board without Ethernet it read the radio from the wrong place.
--firmware <firmware.bin> updates the device through /updateFirmware and
checks it still runs a minute later, after it marks the update good.
wait_for_restart compared uptimes, so a test run right after another
restart could see more uptime than before and fail. It compares boot
times, and waits while the device hasn't restarted yet.
