Sometimes I need to modify some configuration files in installed packages. For example I modified /etc/pam.d/polkit-1 file and after I tried modified file I forgot its original version so I removed it hoping that reinstalling policykit-1 package would replace it, so I did
sudo apt-get install --reinstall policykit-1
but it did not replace it though /etc/pam.d/polkit-1 belongs to policykit-1
I also I tried sudo apt-get -o Dpkg::Options::="--force-overwrite" install --reinstall policykit-1 though --force-overwrite option used to override files installed by different packages.
Would anybody tell me how to do that with apt-get? I need to know it because I frequently modify files in my system. Though I can fix it manually.
