I have a software package[1] that is already being used by multiple users.
Its RPM is created with Cmake.

For historical reasons, the software package installs some files in a subdirectory of /opt.
Consequently, if any of these files is changed, Cmake assumes that since the changed file resides in /opt, it is a configuration file (AFAIK, as only config files should go under /opt), and if a yum reinstall of the package is performed, the changed file is not overwritten.

The obvious solution is to install to a non /opt location, e.g., to /usr.
This would work for new versions, but as I said, I have a user-base where /opt is used.

Any ideas on how to force yum reinstall to overwrite the changed files in the /opt sub-directory?
