It’s looking like this may be related to me using a dev build of resinos vs. production. This thread really helped:

Disable console over Serial in Dev on RPi3?

@floion @Page I had the same problem and this solution works. I have a few question though : Are the remount and reboot only necessary to persist the service state or are they necessary to stop the service ? I tried systemctl stop serial-getty@ttyAMA0.service which didn’t produce any error, but didn’t free my serial port. Is it necessary to do the operation on serial0 and not on ttyAMA0 to make it work ?
