CRIU
A Linux userspace checkpoint-and-restore technology initiated by the Virtuozzo team in 2012 to enable live migration of Linux containers. It is widely integrated into container runtimes such as Kubernetes and Podman, relying on kernel /proc interfaces and ptrace system calls to capture complete userspace process snapshots.

CRIU (Checkpoint and Restore in Userspace) can freeze and rebuild a task tree at the process level, but compatibility across kernel versions and network connections is a difficulty.
CRIU (Checkpoint/Restore In Userspace) snapshot restoration technology can restore function state directly from memory images to optimize cold starts.
CRIU（Checkpoint/Restore In Userspace）项目允许在不终止进程的情况下对其进行完整快照并在之后恢复执行，已被广泛用于容器的实时迁移
