What filesystem comes closest to matching NTFS for support of ACLs, and highly-granular permissioning?

It seems that most other filesystems handle the basic *nix permissions (ugo±rwx), with maybe an addition here or there. Or can be "made" to handle ACLs through the use of other tools on top of the system.

On the wikipedia pages about filesystems (http://en.wikipedia.org/wiki/List_of_file_systems & http://en.wikipedia.org/wiki/Comparison_of_file_systems), it appears that while some do support extended meta-data, none support natively the level of permissioning that NTFS does.

Am I wrong in this understanding?

Solution 1:

ZFS has a good support for enhanced ACLs. Check out the documentation: Solaris ZFS Administration Guide: Chapter 8 Using ACLs to Protect ZFS Files

Maybe this is something you're searching for. :-)

Solution 2:

XFS has built in support for filesystem acls and extended attributes.
