Gentoo does this extremely well.

from the command line you run

bash-2.05b# find /etc -iname '._cfg????_*'

and it will return something like:

/etc/._cfg0000_inputrc
/etc/._cfg0000_rc.conf
/etc/._cfg0000_make.conf
/etc/._cfg0000_make.globals
/etc/._cfg0000_DIR_COLORS
/etc/conf.d/._cfg0000_net
/etc/init.d/._cfg0000_consolefont
/etc/init.d/._cfg0000_checkfs
/etc/init.d/._cfg0000_domainname
/etc/init.d/._cfg0000_keymaps
/etc/init.d/._cfg0000_net.eth0
/etc/init.d/._cfg0000_modules
/etc/init.d/._cfg0000_clock
/etc/init.d/._cfg0000_hdparm
/etc/init.d/._cfg0000_bootmisc
/etc/init.d/._cfg0000_halt.sh
/etc/init.d/._cfg0000_serial
/etc/init.d/._cfg0000_checkroot
/etc/._cfg0000_services
/etc/._cfg0000_fstab
/etc/._cfg0000_group
/etc/._cfg0000_hosts
/etc/._cfg0000_issue
/etc/._cfg0000_dispatch-conf.conf
/etc/._cfg0000_shells

These are the config files that are in need of possible updates.

There is an app called etc-update that you can run after updates that will 
enable you to interactively update your config files or you can do it 
manually with diff.
