I was surprised too, when I found the scripts for the kernel in unattended-upgrades. Please note that in Ubuntu update-notifier-common also ships a similar hook: /etc/kernel/postinst.d/update-notifier -> /usr/share/update-notifier/notify-reboot-required I agree that packages should ask for reboot themselves, but I'm OK with keeping the current logic in u-u for the kernels. Regarding the policy change I'd also mention /var/run/reboot-required.pkgs , like this: Maintainer scripts can signal that a reboot is required to fully apply the changes to the system by touching /var/run/reboot-required and adding the package name to /var/run/reboot-required.pkgs. Maintainer scripts should not add the package name to /var/run/reboot-required.pkgs if it is already present there.
