Groovy for System Administrators
summary
Argues servers should be built reproducibly as part of the build pipeline, not left 10% done for config management; demonstrates a Gradle provisioning plugin that creates an unattended ISO, builds an RPM from a Ratpack fat‑jar, provisions a VirtualBox VM and boots a working Hello World. Shows Grails/Spring Security used for PAM auth via Grails‑based auth and a proof‑of‑concept kernel module + UDP that intercepts mkdir and asks a Groovy listener to allow or deny, and it works end‑to‑end.
