> И для xattr:
> The vfs_acl_xattr VFS module stores NTFS Access Control Lists (ACLs) in Extended
> Attributes (EAs). This enables the full mapping of Windows ACLs on
> Samba servers.
> The ACLs are stored in the Extended Attribute security.NTACL of a file
> or directory. This Attribute is not listed by getfattr -d filename.
> To show the current value, the name of the EA must
> be specified (e.g. getfattr -n security.NTACL filename ).
> Please note that this module is experimental!
