dbfs as a service

[nocentino]

I noticed when running dbfs, it detaches from the terminal and stays running when I log out of the system. While this is fine as a proof of concept, if we want dbfs running as a service this should be managed by the initialization daemon of the system...systemd or initd. If it's a user process, allow me to choose to background it with & as we would any other user process.

This is an interesting point. I believe it would make sense to have it running as service. I will look into changing this.
