kernel-common asks to overwrite /etc/kernel-img.conf during 14.10 upgrade from 14.04

I was upgrading to the development version of 14.10 today, and kernel-common asked about the config file /etc/kernel-img.conf. I don't know how to handle the issue, but the file content report that the contents are only there for legacy use. Should it consider just overwriting that file in all cases instead of asking a user?

Here's the version info after the upgrade:
$ dpkg -l kernel-common
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Architecture Description
+++-==============-============-============-=================================
ii kernel-common 13.014 all common elements for generated ker

I am pretty sure I was at the latest version in 14.04 before the upgrade. My /etc/kernel-img.conf was an empty file. I don't remember ever editing that file.
