TL;DR: In reference to my testcase: BAD: tar -c -f /tmp/test.tar -C dir subdir --exclude subdir/file FIXED: tar -c -f /tmp/test.tar -C dir --exclude subdir/file subdir Clarifying last bits with upstream, but this probably is a regression for everybody who used it wrong (like me) in the past. ** Bug watch added: Debian Bug tracker #824902 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=824902 ** Also affects: tar via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=824902 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to tar in Ubuntu. https://bugs.launchpad.net/bugs/1588690 Title: Tar fails to --exclude files Status in GNU tar: Unknown Status in tar package in Ubuntu: Confirmed Status in tar package in Debian: New Bug description: Hi, this is a regression in tar 1.28-2.1 -> 1.29-1 and by that it is valid for Xenial -> Yakkety, but as well for Debian Stretch. Fortunately there is at least a simple test: rm -rf dir; mkdir -p dir/subdir; touch dir/subdir/file; tar -c -f /tmp/test.tar -C dir subdir --exclude subdir/file; tar -tf /tmp/test.tar subdir/file Correct: tar: subdir/file: Not found in archive tar: Exiting with failure status due to previous errors Wrong: subdir/file This could cause quite a few weird/under-the-radar bugs all around - like in my package which suddenly had more binaries. "Fortunately" one of them collided with one of the system, so we found this issue. I'll report to Debian as well and link the bug.
