notes "

You can add the following line into \"${ndnxdir}/ndndrc\" in order to automatically
start ndnx repo for the /ndn/keys prefix:

    NDNR_GLOBAL_PREFIX=/ndn/keys

For more information and documentation, refer to man pages and http://www.ndnx.org website.

If you have your public key signed by NDN testbed operators and you installed the certificate
\(using ndn-install-pubcert command\), you can enable automatic configuration of the default
route using your key.  To do so, you need to run the following commands once:

  # extract public key from ndnx user
  sudo HOME=${ndnxdir} ndn-extract-public-key > /tmp/ndnx.pem

  # sign public key of the ndnx user
  ndn-sign-key -i \"ndnx-autoconfig\" /tmp/ndnx.pem

  # install certification of the public key
  sudo HOME=${ndnxdir} ndn-install-pubcert /tmp/ndnx.pubcert
