25
26
27       --work-path path
28              Set  path for saving criu work files and logs. The default is to

36       --leave-running
37              Leave the process running after checkpointing.
38

40       --tcp-established
41              Allow checkpoint/restore of  established  TCP  connections.  See

43              tablished⟩.

58
59
60       --status-fd fd
61              Pass a file descriptor fd to criu.  Once  lazy-pages  server  is
