Is there a preferred method to daemonize a vagrant plugin?
I am using vagrant-fsnotify which runs a process on the host to send file change events from the host to the guest.
Vagrant plugins have access to Vagrant "Action Hooks" which are useful for extending expected events.
For example, I could extend the fsnotify functionality to use Daemons for background-processing capabilities. Then, tie into the Vagrant Action Hook up and halt to trigger the start of fsnotify, and trigger the stop of fsnotify.
Here is a good example vagrant-plugin that uses action-hooks.
