You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: start_linux.go
    path of file: ./repos/moby/daemon
    
    the code of the file until where you have to start completion: package daemon // import "github.com/docker/docker/daemon"

import (
	"context"
	"fmt"

	specs "github.com/opencontainers/runtime-spec/specs-go"

	"github.com/docker/docker/container"
	"github.com/docker/docker/errdefs"
	"github.com/docker/docker/libcontainerd/types"
	"github.com/docker/docker/oci"
)

// initializeCreatedTask performs any initialization that needs to be done to
// prepare a freshly-created task to be start
    
func (daemon *Daemon) initializeCreatedTask(ctx context.Context, tsk types.Task, container *container.Container, spec *specs.Spec) error {
	if !container.Config.NetworkDisabled {
		nspath, ok := oci.NamespacePath(spec, specs.NetworkNamespace)
		if ok && nspath == "" { // the runtime has been instructed to create a new network namespace for tsk.
			sb, err := daemon.netController.GetSandbox(container.ID)
			if err != nil {
				return errdefs.System(err)
			}
			if err := sb.SetKey(fmt.Sprintf("/proc/%d/ns/net", tsk.Pid())); err != nil {
				return errdefs.System(err)
			}
		}
	}
	return nil
}
