I have heard rpmrc is not used anymore. If it is correct, would anybody update manual?
--rcfile FILELIST
Each of the files in the colon separated FILELIST
is read sequentially by rpm for configuration
information. Only the first file in the list must
exist, and tildes will be expanded to the value of
$HOME. The default FILELIST is
/usr/lib/rpm/rpmrc:/etc/rpmrc:~/.rpmrc.
