First I followed your advices and I successfully tested the sample script you suggested without modify it. Then each time I attempted to add a line to the same file, it wasn't executed anymore. I read the file with cat -T /media/openstack/latest/user_data and then noticed that the lines weren't uniformly formated : some were with tab and other ones with 8 spaces. Following "Please note that you need to add a tab/4 spaces as shown above" I added tab on every lines related to content of the file, but it didn't work. I began again with only 8 spaces and then it ran. Seems YAML to be very format sensitive and it is not clear enough when begining this kind of job, so that I hope my leak will help many other ones. I think the custom script field in the UI is not helpful because it is impossible to insert a line, when doing a CR it leads to the end of file, and it is a behaviour which easily leads to format error. It could be a good idea to refuse validating OK if any tab is detected there. Can I have your feeling about this?

Copy/past is the best way for not having tabs instead of the correct 8 spaces before each file content instruction
