Are per-file and directory access permissions for an user or a group stored as part of the NTFS structures on-disk? Or are they recorded in the registry database for an installed Windows OS, or elsewhere yet?
In practice, assuming several NT-class OSes accessing common HD volumes, can I safely make mods/repairs to the access permissions on one without affecting the other windowses? In other words, will any file system object's permissions that are set/modified while running OS 1 affect the permissions applicable to the same object, as seen while running OS 2 at a later time?
The question is limited to Windows NT type operating systems only.
