[16:40] <Guest14> Hi, Any reason why my userdata script runs twice on ec2. instance?
[16:52] <holman> Guest14: you'll need to include more details than that
[16:54] <holman> Guest14: version, distro, logs, and user-data would be a good start
[17:10] <holman> Is this on multiple boots or same boot? 
[18:14] <Guest14> same boot. arm - graviton c6
[19:10] <minimal> Guest14: as holman indicated you need to provide more information, specifically the cloud-init.log
