From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Sorry, but this is completely wrong.

Windows has ACLs and they are an important part of Windows administration, and used extensively for managing file permissions.

Windows has supported ACLs on NTFS since Windows NT & NTFS were released in 1993 (~~possibly partly influenced by AIX ACLs in the late 80s~~ influenced by VMS ACLs introduced the early 80s).

ACLs were not introduced to standard POSIX until c.1998, and NFS and Linux filesystems didn't get them until 2003. In fact, the design of the NFSv4 ACL standard was heavily influenced by the design of NTFS/Windows ACL model -- a specific decision by the designers to model it more like NTFS rather than AIX/POSIX.

Technically, at the filesystem level, exFAT also provides support for ACLs, but I am not sure if any implementation actually makes use of this feature (not even Windows AFAIK, certainly not any desktop version).

Damn, giving me flashbacks of slowly moving through ACLs then hitting domain groups, domain local groups, global groups, then eventually universal groups as AD moved forward in complex situations.

Got to admit it worked well though.
