ntp support installation

[Default User]

Hi guys. 

I did a fresh Ubuntu 7.04 install.  Then I used Update Manager to
install all updates.  Then I went to the Date/Time GUI utility to get
the system to start synchronizing the time with online servers. 

The utility said that it needed to download and istall NTP support. I
clicked OK. During the NTP install operation, it said that a
configuration file on the system was different from what was included by
the package maintainer, and asked if I wanted to: 

- keep the original file on the system (the default highlighted option)
- replace with the package maintainer's version

Not knowing which was the correct answer, I chose to keep the original
file. The installation finished with no (apparent) error message. 

Then in a window with a scroll bar I clicked on a local NTP server, and
a "semi-local" NTP server also. At the bottom of the window there was a
choice with the check box highlighted by default, but no name next to
it. I left that checked.  

Well, it seems to be working, but the question is, when I had to choose
between the configuration file already on the system, or the package
maintainer's version, WHICH SHOULD I HAVE CHOSEN?  If I have chosen the
wrong option, I would like to know now, so that I can rip out this
Ubuntu installation and re-install Ubuntu from scratch, before it is too
late to do so. 

Note: This Ubuntu installation was actually a complete re-install of a
prior fresh 7.04 installation, necessary because I found out that the
OpenBSD install disk is like a child that does not play nice with
others. But that's another story. 

The point is, should I have used dd to "zero out" the hard disk before
re-installing Ubuntu?  Since Ubuntu's installer re-partitions the hard
disk, I didn't think that would be necessary. But maybe the NTP
installation was seeing a configuration file from the prior
installation, thus asking which file to use?
