+ Copy hook
+
+ If the container being copied has one or more
+ lxc.hook.clone specified, then the specified hooks
+ will be called for the new container. The first 3 arguments passed to the
+ clone hook will be the container name, a section ('lxc'), and the hook
+ type ('clone'). Extra arguments passed to lxc-copy will
+ be passed to the hook program starting at argument 4. The
+ LXC_ROOTFS_MOUNT environment variable gives
+ the path under which the container's root filesystem is mounted. The
+ configuration file pathname is stored in
+ LXC_CONFIG_FILE, the new container name in
+ LXC_NAME, the old container name in
+ LXC_SRC_NAME, and the path or device on which the
+ rootfs is located is in LXC_ROOTFS_PATH.
