Youngsters these days.....

I still have painful memories of an environment with too many filesystems 
cross mounted between workstations and (at the time big) minicomputers. 
All too often someone would shut down a workstation that was serving a 
filesystem and everything would crash.  Just like dominos.

Like I said, a sordid history.
