Building elastic configurations using CentOS Stream and EC2-Hibernate
summary
Enables EC2 hibernation on CentOS Stream by adding swap file support and an ec2-hibernate agent plus kernel and XFS fixes; upstream patches land in Fedora so CentOS Stream builds include the components. Deploys via CloudFormation or launch templates, requires an encrypted root >16GB EBS volume, targets Nitro/KVM instance types (t3/c5/m5), and excludes older Zen-based generations. Testing saves PIDs, hibernates, restores, and verifies processes and filesystem integrity — functionality works after the fixes.
