[Gnumed-devel] debian install gnumed-client 0.3.10-1 package overwrites

When doing

        apt-get install gnumed-client (3.10x)

I got a prompt for a decision on overwritng the ntp configuration file. While ntp was not a part of my debian lenny (business iso installation with tasksel as Desktop environment, Laptop Sql database) an /etc/ntp.conf might have been created by my attempt to select "Keep synchronized" in my Gnome desktop "Time & Date" panel at which time it complained about the lack of ntp being installed. After I installed gnumed-client and then returned to Time & Date I discovered that the ability to keep synchronized had become enabled.

Can the gnumed-client .deb provide additional information to help the installing user to know if it would be safe to overwrite an existing ntp.conf file, or to suppress such a prompt by removing the choice from the user and just overwriting the file? Or should a user be warned to recheck if their system was no longer pointed to suitable servers?

FYI I chose "D" in order to generate the output at bottom, and then accepted to install the package maintainer's version.

Setting up ntp (1:4.2.4p4+dfsg-8) ...

Configuration file `/etc/ntp.conf'
 ==> File on system created by you or by a script.
 ==> File also in package provided by package maintainer.
   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.
*** ntp.conf (Y/I/N/O/D/Z) [default=N] ?

==================================================================
Here was the output of selecting "D"
