tar/TODO

Suggestions for improving GNU tar.

* Incorporate fixes from major distributions, e.g., Debian GNU/Linux.

* --append should bail out if the two archives are of different types.

* Add support for GNU private keywords in POSIX 1003.1-2001 headers,
so that the GNU extensions (--incremental, --label and
--multi-volume) may be used with POSIX archives.

* Add support for a 'pax' command that conforms to POSIX 1003.1-2001.
  This would unify paxutils with tar.

* Remove command-line incompatibilities between GNU tar and UNIX tar
  as specified by UNIX98.  The main problem is:

     l   GNU tar doesn't cross filesystem boundaries.
	 UNIX98 tar warns if all links cannot be resolved.
	   (GNU tar --check-links option)

  Perhaps we could announce a phase-in period where "l" changes in semantics.
  In the meanwhile we could make the "l" semantics to be determined by the
  value of POSIXLY_CORRECT variable.

* Interoperate better with Joerg Schilling's star implementation.

* Add an option to remove files that compare successfully.

  It would be useful to be able to use '--remove-files' with '--diff',
  to remove all files that compare successfully, when verifying a backup.

* Add tests for testing the added functonality.

* Consider this:

  What I would like to do is:

  foo my.tar.gz | tar -xzOf - | tar -cMf - -L 650000 - | bar

  where 'foo' is a program that retrieves the archive and streams it
  to stdout and bar is a program that streams the stdin to CDR.
