The main problems are: + + l GNU tar doesn't cross filesystem boundaries. + UNIX98 tar warns if all links cannot be resolved. + (GNU tar has no similar option.) + + o GNU tar says output old format. + UNIX98 tar says don't chown files after extracting + (GNU tar uses "--no-same-owner" for this). + + Many people rely on GNU tar's "l" and "o" so we can't abruptly change + GNU tar to be compatible with UNIX98 tar. + + However, "o" is relatively easy: we can extend GNU tar so that "o" is + a synonym for --no-same-owner when extracting, keeping "o"'s current + semantics when creating. This is a bit of a hack, but it shouldn't + break things. + + "l" will be harder, since it's a clear incompatibility. Perhaps we + could announce a phase-in period where "l" changes in semantics. + However, the first step should be to support the UNIX98 semantics, + using a long option, without changing the meaning of "l" for now. That + will give people a migration strategy. + +* Interoperate better with Joerg Schilling's star implementation. + +* Add an option to remove files that compare successfully. + + From: Roesinger Eric + Date: Sat, 28 Jul 2001 18:43:43 -0500 + + It would be useful to be able to use '--remove-files' with '--diff', + to remove all files that compare successfully, when verifying a backup. + +* Copyright notice + + Copyright (C) 2003 Free Software Foundation, Inc. + + This file is part of GNU tar. + + GNU tar is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2, or (at your option) + any later version. + + GNU tar is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
