It's also impossible for exim4 for work immediately after installation without an automatic configuration. Packages need to work immediate after installation so that other packages can use them during their installation. Distribution-shipped configuration files aren't going away. Perhaps they should be moved to somewhere you don't see them -- like /usr/share -- and then overridden with your configuration in /etc, but they aren't going away. If you want to use your version of the configuration file, but tell dpkg not to use the maintainer's version; it'll ask you before replacing files marked as conffiles. >> For those who prefer a single file, debconf allows that, satisfying all >> kinds of people.

While I would don't see myself using single-file exim4 configurations in the future, I certainly think it should be an option. I used to use /etc/apt/sources.list.d, but now I think I prefer the /etc/apt/sources.list approach. It's supposed by more programs and my list never gets over 24 lines anyway. >> > Just >> > packages like exim4 or apache2 that use an approach which makes it >> > very difficult to impossible for the administrator to configure them >> > break it. >> >> That's your opinion.

I even split up my configuration across multiple files. It's nice to be able to disable just a single site with a single command (okay, two; apache2 has to reload the configuration) rather than commenting out multiple set of lines and hoping I've got it all. >You can try it by, for example, installing php >for apache2.

Done it, for running Drupal. Yes, I had to ask apache to re-read it's configuration files. That's about it, and I was expecting that. >Exim4 is another example.

You are basically worried about the behavior you haven't specified changing. Unfortunately, even with a single file that can happen due to changes in the source code. If you need specific behavior, don't default to it, explicitly specify it. Personally, I only needed to tweak things in the exim4 configuration, so most (maybe all) of my changes were adding files to the existing directory structure. The split in to multiple files made it easier to work with. >> I don't know about apache, but as I said, with exim it's quite easy >> to use a single file, if you prefer it that way. > >Well, where is the option to have the automatic configuration create a >single configuration file that you can easily check and then use to >configure your program if you want to? Do you mean specifically for exim4? I think the option to use a single file is the first or second question asked by dpkg-reconfigure exim4-config. -- Boyd Stephen Smith Jr. ,= ,-_-. =. firstname.lastname@example.org ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.org/ \_/
