The logs are mostly useless and random. There is nothing that consistently appears between the point where it finishes mounting (lots of "Mouting...", then "Reached target Local File Systems") and where it starts unmounting ("Stopped target Local File Systems", then lots of "Unmouting ..."). Sometimes these two lines are less than one second apart. But I haven't found any message which is consistently between these two points that would point to a suspect. And this is not a problem that happens on every boot, so it doesn't show up on analysis... not to mention that most of the analysis is designed on trying to reduce boottime, which obviously is no help (thought it is rather fast already). It is rather easy to guess why a service is starting, but not why it decides to stop 'orderly', much less why a .target decides to stop...
