# Version stamping for the environment file and for the config.json file.  Will be used to determine
#   if those files need to be recreated by the update service.
#
# config-lcwa-speed-sysprep.sh updated to enable systemd-timesyncd.service and systemd-time-wait-sync.service
#
# config-lcwa-speed-services.sh updated to add Wants= & After=systemd-time-wait-sync.service so that RPi systems
#    will have gotten an ntp time sync from systemd-timesyncd.service before our service starts.
