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: docker.go
    path of file: ./repos/moby/cmd/dockerd
    
    the code of the file until where you have to start completion: package main

import (
	"fmt"
	"os"
	"os/signal"
	"syscall"

	"github.com/containerd/log"
	"github.com/docker/docker/daemon/config"
	"github.com/docker/docker/dockerversion"
	"github.com/docker/docker/pkg/reexec"
	"github.com/docker/docker/pkg/rootless"
	"github.com/moby/buildkit/util/apicaps"
	"github.com/moby/term"
	"github.com/spf13/cobra"
)

var honorXDG bool

func newDaemonCommand() (*cobra.Command, error) {
	// FIXME
    
func main() {
	if reexec.Init() {
		return
	}

	// Ignore SIGPIPE events. These are generated by systemd when journald is restarted while
	// the docker daemon is not restarted and also running under systemd.
	// Fixes https://github.com/docker/docker/issues/19728
	signal.Ignore(syscall.SIGPIPE)

	// Set terminal emulation based on platform as required.
	_, stdout, stderr := term.StdStreams()
	onError := func(err error) {
		fmt.Fprintf(stderr, "%s\n", err)
		os.Exit(1)
	}

	// initial log formatting; this setting is updated after the daemon configuration is loaded.
	err := log.SetFormat(log.TextFormat)
	if err != nil {
		onError(err)
	}

	initLogging(stdout, stderr)
	configureGRPCLog()

	cmd, err := newDaemonCommand()
	if err != nil {

	}
	cmd.SetOut(stdout)
