Thank you for sharing, because I didn't know what cloud-init was until your post. I've done something similar, but packaged as a library of bash functions, designed to be called in arbitrary order. I cannot comment on the specific decisions you made in your file, but the fact that a declarative, compact, and standard solution exists for this problem is music to my ears. Out of curiosity, where did YOU learn of the existence of this feature?
