 Iggy server uses `io_uring` for high-performance async I/O. This requires:
 
-1. **IPC_LOCK capability** - For locking memory required by io_uring
-2. **Unconfined seccomp profile** - To allow io_uring syscalls
+1. **Required io_uring setup features** - The node must provide both flags:
+
+   * `IORING_SETUP_COOP_TASKRUN`
+   * `IORING_SETUP_TASKRUN_FLAG`
+
+   Mainline Linux provides both starting in 5.19. Vendor kernels may backport them to older kernel versions.
+
+   The server fails during startup if either is unavailable. Node capabilities matter, not the container image.
