  [Regression Potential]
  Minimal - the fix is limited to a single line in the pre-start block of the nmbd upstart configuration.  Any regressions would manifest themselves in this area. Likely problems may include nmbd itself (rather than the upstart pre-start script) not starting correctly due to broken configuration - although this is not technically a regression of course.
