From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.1-0.1.14 i686) The arguments to "tar" for decompressing bzip2'd files on-the-fly have changed since the 7.0 release; instead of using "-I" for decompressing bzip2'd data, the argument is now "-j". "-I" is completely ignored. Reproducible: Always Steps to Reproduce: cp /etc/passwd blah.txt tar cvvf blah.tar blah.txt bzip2 -9 blah.tar tar Ixvvf blah.tar.bz2 (on 7.0) tar jxvvf blah.tar.bz2 (on fisher or wolverine) Not that this is a real painful change, but it appears to have been gratuitously made incompatible without any documentation of the fact. Looks like a note for the release notes, more than anything.
While this is not a bug, we agree and reverted tar to the old behavior in 1.13.19-2.
