Thank you for your explanation.
I would like to prepare an Oracle Database image based on the CentOS 7.1 one-marketplace image and I would like to make sure that all one-context scripts will re-run after the new image is started.
Based on this procedure, should only have to remove all one-context* packages and reinstall them?
For cloud-init, deleting all files in the /var/lib/cloud/instance/sem/ directory do the job.
Thanks again and happy new year!
Just realized that the one-context scripts are executed at each boot. My bad.
