- 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.
+ Currently tar prints a warning when this option is used. Sometime
+ in the future its semantics will be changed to that of --check-links.
+ In the meanwhile we should announce a phase-in period where "l"
+ changes in semantics.
