I've some ideas, but no final proposition. Some thoughts:
- to be able to know :
* the old file and the new (proposed) one before merging
* the new file after merge (can be difficult if the 'merge' is done
manually after the package installation) => should probably be done
as currently by etckeeper, ie with a apt hooks after installation
and a crontab job.
* all of this with the package (and the versions) involved
- to be able to propose new merge strategies:
* 3 ways merges even for packages that does not use the --three-way
option
* cme based merge/update (if possible)
* specific merge strategies provided by other tools (for all or for
some config files)
- to be able to ask dpkg to use ucf (or to use the same callback
and extended merge strategies) [because ucf does not cover lots of
config files for now]
- to improve dpkg so that ucfr can register files into the dpkg file
database (so that dpkg -S also works)
And, after the current discussion, I have new thoughts for more complex
things:
- to be able to track external directory (/usr/...) as 'models' for
config files and to present the same kind of resolution conflict
when a file in /etc is present that override a modified default config
file in /usr
This can be a bit more difficult to integrate if we want to be
able to do a kind of 'git diff official..master' to get only local
config modification. And if we want to support partial override (such
as services.d systemd directories)
