# Traditionally, and to some extent still, rpm --freshen upgraded
# packages that matched by RPMTAG_NAME, not RPMTAG_PROVIDENAME.
#
# This freshen.sh script illustrates how to revert to the "traditional"
# behavior for doing, say,
#	rpm -Fvh kernel-bigmem*.rpm
# so that only kernel-bigmem packages are upgraded, rather than
# upgrading (i.e. erasing) every kernel package that contains
#	Provides: kernel = V-R
#
# Copy the freshen.sh script to /usr/lib/rpm, and add the following
# lines to /etc/popt to enable the behavior:
#	rpm alias -F		--freshen
#	rpm exec --freshen	/usr/lib/rpm/freshen.sh
#
