## Download and configure some images, and write out glance commands to
## get them uploaded into glance.  This script only runs the upload
## commands if we're not being run from controller setup; otherwise, the
## controller setup process runs this when it is safe (if in controller
## setup, we don't upload them into glance immediately because glance
## might not be running or any number of components may be restarting or
## otherwise in flux; setup-basic.sh uploads them when it is safe, near
## the end of our setup).
