This would unify paxutils with tar.
* Remove command-line incompatibilities between GNU tar and UNIX tar
- as specified by UNIX98. The main problems are:
+ 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 has no similar option.)
+ (GNU tar --check-links 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.
+ 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.
