Avoid apt prompting on modified pkg files, and instead keep the modified files

[piavlo]

Hi,
I have several files i have modified and every time there is a new version for package (which contains the modified file)
I get prompted if i want to keep or override the modified file.

Setting up apt (0.7.6ubuntu14.1) ...

Configuration file `/etc/cron.daily/apt'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : background this process to examine the situation
The default action is to keep your current version.
*** apt (Y/I/N/O/D/Z) [default=N] ?

Is there an option to tell apt to keep the modified files,
since i'm running updates unattended?

I think you can get the behavior you want using either aptitude hold from the command line or the Package -> Lock version menu pick in Synaptic.

Have you read into the dpkg docs? They control a lot of the prompts that appear after apt has run.
