From: Oren Laadan <orenl@xxxxxxxxxxxxxxx> Create trivial sys_checkpoint and sys_restore system calls. They will enable to checkpoint and restart an entire container, to and from a checkpoint image file. First create a template for both syscalls: they take a file descriptor (for the image file) and flags as arguments. For sys_checkpoint the first argument identifies the target container; for sys_restart it will identify the checkpoint image.
