# This should only be ran during straight updates during a minor release cadence.
# In the case of point releases, this will need to be changed accordingly so that
# way it can be ran properly.
#
# The point of this script is to basically allow all old versions of a package
# or set of packages to be available during the life of a point release. As it
# currently stands, CentOS has started doing this for both 8 and 8-stream. RHEL
# also does this (and has always done this, except they take it a step further
# and provide everything, even if it's not installable).
#
# Compose dir example: /mnt/repos-staging/mirror/pub/rocky/8.4-RC2

# Source common variables
export RLVER=8
