dump/restore, in all its various flavors, is FS-type and/or OS-type specific. It thus can include features specific to those FS/OS. ACL features are not consistant in what and how they are implemented; they too are FS/OS specific. Thus, dump/restore can handle them. Tar, OTOH, is intended to be FS/OS non-specific. Thus it handles a subset of all possible FS/OS features, namely those common to all and present since the early days of unix. -- Jon H.
