Updating rpm commands
Each of the files in the colon separated FILELIST is read sequentially by rpm for configuration information.
Only the first file in the list must exist, and tildes will be expanded to the value of $HOME.
Fedora/RHEL have system-config-network, ubuntu pre 10.04 had gnome-nettool to edit static ip address, since 10.04 nm-connection-editor is the best choice.
Of course, if you did not keep a good record of what packages actually were changed and what their previous versions were, things got even worse.
RPM can be used to install and remove software packages, update packages and get an overview of all installed packages.
