dpkg-reconfigure gives a way to set options for installed packages in a "user-friendly" way (e.g. not editing files but selecting from dialogs).
How can I find out what package has such options? e.g. "
dpkg-reconfigure tzdata" does have it while "
dpkg-reconfigure nano" does not.
What's the correct argument/package to add an additional
dpkg-reconfigure the "dialog-way"?
