if it is added, file systems you are importing may not disallow it even
though your local systems do.  net effect: you won't be able to access
bizarrely named files on the the nfs filesystems if it's a system wide
variable.  in which case, filesystems by filesystem seems to be the
way to go...

perhaps it should be another mount-flag?  the effects of which can be
controlled by a sysctl?
