I think it might be nice to have a feature that you can set as a flag possibly on etc-update, that will safely merge all config files. ie: inset new lines, and do not change existing ones. for major changes skipt he file and notify the user. it would save a lot of time doing things that usually will not change.
Sure, it would be nice. How feasible is it? Don't know. As far I'm conserned, there is no such thing as "safely merging all config files" without being somehow manually interactive. Adding new lines to a config file *could* b0rk your setup, and it could of course be totally harmless (like comments and headers), but how can etc-update decide what's harmless? Ideas are welcome :) Just my $0.02
No. interactivity is necessary in merging config files, no questions. We are however trying to make etc-update much less annoying. I'm going to mark this one a duplicate of bug 3804 *** This bug has been marked as a duplicate of 3804 ***
Look to FreeBSD's mergemaster ... it can merge the conf files together, so its possible ... . But if u dont add such a feature, please change the words which describe the action, merge should be a overwirte in case of dont editing it with the editor. It prevents some really anoying work to revocer the configuration files, because it does not do what "merge" is meaning, it overrides the files, dont merge them - so please change your choice of words.
