`/etc/kernel/postinst.d/nova-kernel-permissions.sh` (introduced to fix Bug #1507915) is supposed to make newly installed kernels readable to the nova user, as kernels on an Ubuntu system are otherwise only readable to the root user [0]. This script didn't work for a few reasons: - It never ran, because scripts in `/etc/kernel/postinst.d` are called by `run-parts`, and run-parts skips any script with a period in the name [1]. - Its shebang was missing its bang - If installation of the same kernel is installed more than once (e.g. reinstallation), `dpkg-statoverride` (and the whole kernel installation) would exit with error, complaining about an override already existing [2]. Fixed with these changes respectively: - Renamed script to remove the period - Fixed typo in shebang - Added `--force` flag to `dpkg-statoverride` [0] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/759725 [1] https://bugs.launchpad.net/ubuntu/+source/debianutils/+bug/38022 [2] https://bugs.launchpad.net/openstack-manuals/+bug/1275080 Change-Id: I0e130e3c3ecf2171dbdc0e9a809f8066c30d4bc9 Closes-Bug: 1763479
