## Background Execution
If the command you specify runs in the background (such as appending a `&` to
a shell command), it will be terminated almost immediately. This is because
when Vagrant executes the command, it executes it within the context of a
shell, and when the shell exits, all of the child processes also exit.
To avoid this, you'll need to detach the process from the shell. Please
Google to learn how to do this for your shell. One method of doing this is
the `nohup` command.
