Sorry, I didn't explain well. I was referring to the "format" of the file, i.e. the allowed internal structure of it. It may happen, of course, that the file provided inside the .deb changes, but if I already changed my own version to point to a local mirror, it is unlikely that I want to use again the sources.list pointing to a far mirror site in another continent, unless the new APT does not accept my old file and I have to change its internal format. A few examples in which having the configuration file to be generated in the postinst has had a clear benefit: /etc/papersize Once you have chosen your desired paper format, it is a good thing that dpkg does not ask you over and over again about this file. Since Europe uses "a4" mainly and the US uses letter (I think), there is not a common "default" configuration file which is valid for everybody, and it makes sense for it to be generated in the postinst when it does not exist. /etc/gpm.conf Once you have chosen your desired mouse type, it is a good thing that dpkg does not ask you over and over again about this file. Since there are many different mouse types, there is not a reasonable default valid for everybody and it makes sense for this file to be generated by the postinst when it does not exist. Of course, I'm not saying that every configuration file should be like these ones, but I think that the current /etc/apt/sources.list is of the type of file that, when generated in the postinst, would reduce the amount of total prompting dpkg does when upgrading. I think there are two issues to consider here: 1. Is http://http.us.debian.org a reasonable default for *everybody* or just for the US? 2. Is the format of the file expected to change sometime soon?
