Conf-update

[conf-update Homepage] (an honest to God gopher site! wow!)
There isn't a whole lot to do with this ... I just modified /etc/conf-update.conf to my taste and run conf-update after every install and/or update. Here's a short blurb from the home page:
What is conf-update?
conf-update is a tool which facilitates the configuration management on Gentoo systems.
It features a ncurses-based menu that shows all the config files with updates scheduled in a folded directory tree and allows quick replacing, merging, removing, diff viewing and editing of configuration updates.Further, it stores a hash index to detect config files that were not touched by the user to automatically replace them with the new version. Updates that only affect comments are also automatically put into place if conf-update was configured to do so. It is a menu-driven application written in C and has a TUI that resembles Linux' "menuconfig".
conf-update was designed with big queues of updates in mind, so if you happen to not touch your system as long as it works fine but only update it if you absolutely have to (your current gcc version is no longer supported, rebuilding the whole system is necessary because of ABI changes; a new security update pulls in a large chunk of dependencies, just to name the two most popular reasons), this tool will probably be much friendlier than etc-update or dispatch-conf.
