When trying to uncompress archives, this happens a lot with 1.13.18-1 (this is an example with the gdb source archive shipped with Red Hat Linux 7): [teg@halden src]$ tar Ixf /usr/src/redhat/SOURCES/gdb-20000725.tar.bz2 tar: This does not look like a tar archive tar: Skipping to next header tar: 40 garbage bytes ignored at end of archive tar: Error exit delayed from previous errors [teg@halden src]$ rpm -q tar tar-1.13.18-1 [teg@halden src]$ rpm -q tar tar-1.13.17-8 [teg@halden src]$ tar Ixf /usr/src/redhat/SOURCES/gdb-20000725.tar.bz2 [teg@halden src]$
They've changed the bzip2 option, it's now "j" rather than "I" for compatibility with Slowlaris. I've mentioned this on the develdept list when I instrooted the new tar.
