 // Defines the BootloaderType class.  This class wraps the kernel commandline
 // to determine the bootloader type.  Our bootloaders are configured to boot
 // with identifying kernel command lines:
 // - EFI uses cros_efi
 // - Legacy uses cros_legacy
 // - Chrome OS uses cros_secure
 // - A debug override can use cros_debug.
 // This done by walking /proc/cmdline.
