Thanks @alberto. I confirmed the following:
The question of whether apt upgrade would show us the Files changed prompt which would break unattended upgrades. The answer is we don't have to worry about it because apt upgrade only reacts to changes in files registered by the deb package as conffiles. Any other non-conffiles are not monitored for that change dialog. From dpkg --status cloud-init or directly at /var/lib/dpkg/info/cloud-init.conffiles we can see that our registered conffiles all live under /etc, so the fact that livecd-rootfs has a modified /lib/systemd/system/cloud-init.service conf doesn't register for apt upgrade type config changed dialogs. That said, any modified path installed which has an md5sum listed in /var/lib/dpkg/info/cloud-init.md5sums would be noted by debsums -c if the md5sum changes on those files. So, there is nothing in cloud-init upstream packaging to do here related to this fix because a modified /lib/systemd/system/cloud-init.service doesn't trigger that prompt on apt upgrade or unattended upgrades. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069391 Title: debsums reports file changed /usr/lib/systemd/system/cloud- init.service To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/2069391/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
