# Update script for mirror.starlingx.windriver.com covering
# yum.repos.d.
#
# IMPORTANT: This script is only to be run on the StarlingX mirror.
# It is not for use by the general StarlinX developer.
#
# Configuration files for repositories to be downloaded are currently
# stored at mirror.starlingx.windriver.com:/export/config/yum.repos.d/
# and /export/config/rpm-gpg-keys. These configuration files need
# to be updated periodically to reflect changes made to
# stx-tools/centos-mirror-tools/yum.repos.d/ and
# stx-tools/centos-mirror-tools/rpm-gpg-keys/.
# The update are additive in nature, mirror.starlingx.windriver.com
# does not delete keys or repos. At worst we will rename a
# repo if it's url has changed.
#
# This script was originated by Scott Little.
