===============================================================================
  Holy cow! Looks like you ran 'npm remove' but without the --unsafe-perm flag.
  This means the init scripts will remain installed, because they need root to be removed.

  To ensure a clean uninstall, please reinstall the package and then re-run this command,
  only this time with the --unsafe-perm flag, so everything gets wiped out:

  $ sudo npm -g remove prey --unsafe-perm
===============================================================================

===============================================================================
  You are running this script as an unprivileged user
  so we cannot finalize setting up the client.
  To continue with the install process please run:

  $ sudo prey config hooks post_install
