  In daemon mode, the system is started on the background via
  [run_erl](http://erlang.org/doc/man/run_erl.html). Running in

  by adding `-heart` to their vm.args file (see a later section
  on customizing vm.args). `heart` automatically restarts the
  system in case it crashes.

  The daemon will write all of its standard output to the "tmp/log/"
  directory in the release root. A developer can also attach
