You're confusing on-disk formats used to store attributes with namepaces used to report and access them. Linux has security, system, trusted and user namespaces, while on disk XFS has "root", "secure", and "user" spaces. i.e. Linux attr XFS on disk system root security secure trusted root user user > Of these, the ACL's are being placed in the root, which might describe > file types, or other OS related info, but not security attributes like ACL's. > They should be in the Security attrib space (otherwise what is the point of a > Security attribute space). Posix ACLS are defined by the *kernel* to be in the "system" namespace: #define POSIX_ACL_XATTR_ACCESS "system.posix_acl_access" #define POSIX_ACL_XATTR_DEFAULT "system.posix_acl_default" IOWs, the Linux *kernel* doesn't consider ACLs to be part of the security namespace, and so neither does XFS.
