> And I cannot get what should be default tar acl behaviour? Thanks for your comment, I missed that the documentation part was not pushed upstream:

What was the reason not to make it like a default? Due to make the ACL proposal as non-invasive as possible (as it was one of the initial requirements for such contribution). Good question would be whether the default may be changed upstream? As a workaround, users are still able to use TAR_OPTIONS environmental variable turning this on by default. Pavel
