I haven't seen the ECDSA key change, but the MAC address does indeed
change on every boot. It seems like the MAC address is derived from the
board serial number, but on my board /proc/cpuinfo reports a 0 serial:

    Hardware    : BCM2709
    Revision    : 0000
    Serial      : 0000000000000000

Maybe Loic or Oliver knows how make a real serial number appear there? I
found some posts related to this issue, but I don't know how they apply
to Snappy.
