the same hard drive for core.img. core.img is at this location and looks
for (,msdos1)/boot/grub. It also embeds following components:

HDDやUSBメモリなどのブロックデバイスを探し出し、属性を表示する「blkid」コマンド

※1 LinuxではHDDやモデムなどの装置を、/dev/sdaのようなデバイスファイルとして管理し
ている。デバイスファイルのうち、アクセス時に文字単位ではなく、ブロック単位でデータ
を転送するものを「ブロックデバイス」と呼ぶ。HDDやCD-ROMなどがブロックデバイスだ
「ls -al /dev」を実行したとき、ブロックデバイスは先頭に「b」と表示される。

※2 UUIDはシステムがランダムに自動生成するほぼ確実に一意な数値である。長さは128
ビット。
