Replace or keep existing configuration files during Linux updates/upgrades

How to handle the apt-get configuration file prompt for /etc/issue when updating or upgrading a fresh Moebius Linux installation on a Raspberry Pi.

During updating/upgrading a fresh Moebius installation on a RaspberryPi with

apt-get update && apt-get upgrade

it brought this question:

Configuration file `/etc/issue'
==> 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     : start a shell to examine the situation
The default action is to keep your current version.
*** issue (Y/I/N/O/D/Z) [default=N] ?

The default hint not to do that is mainly for longer running installations to avoid an overwriting of existing configuration files. In case of a fresh installation you should confirm with Y.
