I agree. 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.
Thanks,
