There is an internal difference with respect to how Upstart obtains the pid of the process, but from
the applications perspective, no there is no difference.

The reason Upstart provides an 'expect' stanza is to allow it to supervise services or daemons which
by design fork either once or twice. If you have an application that does not fork, it is not
necessary to make it fork just to work with Upstart - just don't specify the 'expect' stanza. See
below for further details:
