rpmconfigcheck

sebix

The sections on rpm and yum etc. mention that configuration files are replaced/backuped and saved/renamed as .rpmsave / .rpmnew files. To find them the yum/dnf sections recommends to use find /etc -name ".rpm".

I think it would be a good addition, to mention the program rpmconfigcheck in the zypper section. This programs does check for unresolved .rpmnew, .rpmorig, and .rpmsave files in a bit more advanced way, by also using the rpm database. It's only available on openSUSE AFAIK
