I can't find any changes that would make the syntax change. At least, not in quite a long while. Therefore, this change may not be intentional. However, I looked at the the manual page from 9.3, and its description of the features looks the same as on the latest HEAD, and *doesn't* look like leaving out a "key" (in this case, "compression-level") is ever compliant. You might try the latest (or older) libarchive from the ports, and compare its behaviour. Also, there are a number (amusingly many, in fact) of other ways of specifying these parameters that may be more convenient for you, so another look throught the tar(1) manual might save you a few minutes. Good luck. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
