>On both Windows and Linux, if you have to make changes to FS perms, then the ACLs have to be made to each object - file or folder. On NWFS and NSS, you only do it at a point (say a directory) and then it will recurse automatically unless blocked by an IRF (Inheritable Rights Filter

NTFS has perms inheritance (and overriding) since forever, did you know that?

>The end result is that making a change to a tree of files on any Unix or Windows FS takes from seconds to hours. On NWFS or NSS it generally takes seconds (for the screen to refresh).

Painless administration requires careful planning, no matter what OS you're using.

I think the point was that NTFS has to actually touch the files when they inherit permissions, whereas its better for admin if inheritance works without the files needing to be touched

The inheritable ACLs have to propagate (they can actually get out of sync). This is a design choice; either you check the inherited permissions at file opening or while changing the permissions or creating the file.

Chances are you will open the file more often than you will change ACLs so they chose the latter which makes sense.

Interesting. Do you have any links to read about such implementation details?

This article is about the problems it causes (note that in Vista they changed the design so when moving a subtree the system automatically propagates permissions, removing a major cause of desyncs)
