I've occasionally lost my config file "/etc/mysql/my.cnf", and want to restore it. The file belongs to package mysql-common which is needed for some vital functionality so I can't just purge && install it: the dependencies would be also uninstalled (or if I can ignore them temporarily, they won't be working).

Is there a way to restore the config file from a package without un-ar-ing the package file?

dpkg-reconfigure mysql-common did not restore it.
