21.2.4. Preserving ACLs

The Red Hat Enterprise Linux 4 kernel provides ACL support for the ext3 file system and ext3 file systems mounted with the NFS or Samba protocols. Thus, if an ext3 file system has ACLs enabled for it and is NFS exported, and if the NFS client can read ACLs, they are used by the NFS client as well.
For more information about mounting NFS file systems with ACLs, refer to Chapter 14, Access Control Lists.
