fsaclctl

Enable or disable Access Control List support on a given file system.
Snow Leopard + Lion have ACLs enabled by default and therefore ship without fsaclctl.

After changing Access Control List support either reboot the system, or remount the file system, to make running applications aware of the change.

Syntax
       fsaclctl [-v] [-p -path] [-e] [-d]

Options

     -e      Enable Access Control Lists on the given file system.

     -d      Disable Access Control Lists on the given file system.

     -v      Display version number.

     -p      Path to file system mount point.
             If no options are specified the status of Access Control List support is displayed.

Example
 sudo fsaclctl -p /Volumes/panther -e

Return Values
     0                  fsaclctl Successfully performed requested operation.
     [ENOTSUP]          The filesystem does not support this operation.
     [EPERM]            The requested operation must be performed as root.
