Thanks for the heads-up Balint.
I saw the "full backport" discussion in the ML, thanks !
For now, I'm setting Xenial as 'high' priority as it has been brought to
my attention that 'uu' in Xenial removed a running kernel recently :
/var/log/unattended-upgrades/unattended-upgrades-dpkg.log
...

Bug description:
This may happen, if you boot one of the older kernels, that is not
protected by /etc/apt/apt.conf.d/01autoremove-kernels
Workaround: run
/etc/kernel/postinst.d/apt-auto-removal
during each boot (e.g. by using cron).
Note: The workaround breaks autoremoving feature of new unneeded kernels in
unattended-upgrades i.e. the setting
'Unattended-Upgrade::Remove-New-Unused-Dependencies "true"' (which is default
in 16.04 unless 'Unattended-Upgrade::Remove-Unused-Dependencies "true"' is set
in '/etc/apt/apt.conf.d/50unattended-upgrades'.
In shell:
$ uname -r
4.4.0-22-generic
$ apt-get -s autoremove
NOTE: This is only a simulation!
apt-get needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!
