[Bug 1742903] Re: Microcode updates require a reboot to apply, but package postinst doesn't touch /run/reboot-required

[Dimitri John Ledkov]

I don't think this is high anymore.
Kernel now depends and pulls in microcode packages, and kernel does trigger reboot require notification.
Imho, it is sufficient enough to require reboot from the kernel alone. Since there are frequent enough kernel updates.

  Microcode updates require a reboot to apply, but package postinst
  doesn't touch /run/reboot-required

Bug description:
  The intel-microcode postinst script prints this text to standard error

      intel-microcode: microcode will be updated at next boot

  but tools like unattended-upgrades don't parse stderr, they expect a
  /run/reboot-required to exist to tell them that a reboot is needed to
  complete the update.

  Can you fix the postinst script to touch /run/reboot-required?
