| Why not have a backup of all modified files. Then for uninstall overwrite

you're on the right track for a correct solution (IMHO), but
unfortunately, the suggestion "doesn't work": other changes
(that you wish to keep) may have been made in the interim ....
what I do is use RCS: my static configuration files are kept
under RCS control, which means I not only have a full history
of changes (and hence can backout-and-remerge as the original
problem/question required), and the file itself is readonly
(which is Very Good, IMHO).
CAUTION! this approach is for (wanna-be-)experts/masochists only!
installation/un-installation tools tend not to expect things
to be readonly (and far too often then do the wrong thing);
the RCS/ directories which litter the filesystem not only
need to be backed-up, but are sometimes mis-interpreted as
being "configuration files" (and can be a security hole);
and on and on ....
and what I suggest S/W developers do is junk the monolithic
configuration file (and flat-directory) approach. design so
files, not lines/blocks-within-files, are the atomic units
which are added/modified/deleted.
