You had said that you need to re-install F19. That usually means you
want to re-install all the packages that come with the Operating System,
and the best accompaniment to that is re-formatting the root filesystem.
Just re-formatting the '/boot'/ and 'swap' partitions during re-install
of the Operating System may have different end results depending on what
packages you choose during the re-install.

So the question now arises on why you need to re-install Fedora. Would
your objective be attained with just re-installing packages that you
have some issues with ? Also, the user specific customisations of most
of the applications reside as dot files in the user's home directory, so
re-formatting the root filesystem, and re-installing all the
applications will not impact those customisations, as long as you do not
reformat the home partition. On the other hand, if you are running any
servers, you may need to backup their configuration files before the
re-install, and put them back in after.
