- Add serial to the reboot play so concurrent_reboots controls how many nodes reboot at a time, defaulting to 100% (reboot all at once) for backward compatibility - Add a per-node test_command that verifies the node is healthy after reboot - Add an optional wait_seconds_after_reboot pause between staggered batches so pods can settle before the next batch reboots - Document the new concurrent_reboots and wait_seconds_after_reboot variables Co-authored-by: Felix Seifert <mail@felix-seifert.com>
