CONFIG_CHECKPOINT_RESTORE

[nlienard]

Is it possible to have CONFIG_CHECKPOINT_RESTORE=y in the current kernel on VPS SCALEWAY (VC1L for instance) ?

Currently due to this lack, CRIU is not working and we can't use LXD live Migration.

Does not look good.

# CONFIG_CHECKPOINT_RESTORE is not set

thanks
