示例1: setupBindmounts

func setupBindmounts(rootfs string, bindMounts libcontainer.Mounts) error {
	for _, m := range bindMounts.OfType("bind") {
		var (
			flags = syscall.MS_BIND | syscall.MS_REC
			dest  = filepath.Join(rootfs, m.Destination)
		)
		if !m.Writable {
			flags = flags | syscall.MS_RDONLY

示例2: newSystemMounts

// TODO: this is crappy right now and should be cleaned up with a better way of handling system and
// standard bind mounts allowing them to be more dynamic
