Gentoo uses a bash script called etc-update to do a similar thing.

etc-update is run after an update to merge changes between old and new 
config files.  However the files it merges are in the same location so 
some tweaking would be required.
filenames it uses are of the form:
/etc/._cfg0001_ntp.conf -> /etc/ntp.conf
