#    /config  - containing all the usual EVE configuration files, to wit:
#      * /config/root-certificate.pem (getting replaced by Adam's cert)
#      * /config/server (getting replaced by Adam's local URL)
#      * /config/device.cert.pem (Adam waits for it to show up so it can be registered)
#    /persist - a persistent storage medium where we can keep our state
