Bug Description
Binary package hint: unattended-upgrades
It is possible to restart, shutdown or hibernate the system while a kernel update is installed in the background. This leaves the system unbootable because the inititramdisk and/or kernel image have not been written to disk completely. The same problem may apply to other critical packages, but for the kernel it is especially likely to occur (I already had the problem several times) because running mkinitrd takes quite some time.

Thanks for your bugreport.
I'm adding a linux-source task here. It seems to me like the best course of action here is to modify the building/updating of the initramfs in a way that the time-window were the system does not boot is minimized. Maybe building them all first and then moving them into place once all is done. I don't know enough about the kernel packages.
Cheers,
Michael
