Ok, I'm going to ask.  Normally I would not do so, because I have 
problems believing anyone would ever do this.

Do you, every time, do a proper shutdown of VMS?  Or do you get in a 
hurry and just hit the power or reset switch?

Way back, lo these many years, the prime reason I claimed MS-DOS wasn't 
a "real" OS was because it did not include any shutdown procedure.

Also, mount /norebuild is a very dangerous option, and should only be 
used in emergencies.  My opinion.  YMMV
