我使用 msdos 分区表，所以不支持 PARTUUID（它只在 GPT 分区表上）
root@xenial:~# fdisk -l
Disk /dev/sda: 200 GiB, 214748364800 bytes, 419430400 sectors

那么 blkid 中显示的 PARTUUID 是什么？
root@xenial:~# blkid
/dev/sda1: LABEL="windows" UUID="3364EC1A72AE6339" TYPE="ntfs" PARTUUID="a9ff83af-01"
/dev/sda2: LABEL="/boot" UUID="9de57715-5090-4fe1-bb45-68674e5fd32c" TYPE="ext4" PARTUUID="a9ff83af-02"
/dev/sda3: LABEL="/" UUID="553912bf-82f3-450a-b559-89caf1b8a145" TYPE="ext4" PARTUUID="a9ff83af-03"
/dev/sda5: LABEL="SWAP-sda5" UUID="12e4fe69-c8c2-4c93-86b6-7d6a86fdcb2b" TYPE="swap" PARTUUID="a9ff83af-05"
我需要更改它以调试 ubuntu kickstart 多引导安装，我在哪里可以设置这个 PARTUUID ？
