Thanks for looking at this! I tested your change in Xenial (couldn't install the tools package since i assume you built it against Artful's libraries, but it didn't matter) and it does appear to restore the previous behaviour:
% lsb_release -ds Ubuntu 16.04.3 LTS % uname -r 4.13.0-19-generic % ls -Ali /bin/true /ro/bin/true 131819 -rwxr-xr-x 1 root root 27280 Mar 2 2017 /bin/true 131819 -rwxr-xr-x 1 root root 27280 Mar 2 2017 /ro/bin/true % /bin/true --version | head -1 true (GNU coreutils) 8.25 % sudo cp /bin/true /tmp/ % sudo mv /tmp/true /ro/bin/ % ls -Ali /bin/true /ro/bin/true 131819 -rwxr-xr-x 0 root root 27280 Mar 2 2017 /bin/true 131110 -rwxr-xr-x 1 root root 27280 Dec 8 11:57 /ro/bin/true % /bin/true --version | head -1 true (GNU coreutils) 8.25 (On the 'stock' kernel the last command would produce an error.) I don't see any error messages in the kernel log either. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1736808 Title: Changes to overlay lowerdir produce kernel file-caps error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1736808/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
