You need a backup of the partition table. Which, if you are organized, you already have in $notes_dir/$hostname/install.md as something that looks like this: ``` sudo sfdisk /dev/sdX <<EOF label: gpt unit: sectors sector-size: 512 1 : start= 2048, size= 129024, type=U, name="efi" 2 : start= 131072, size= 976640048, type=R, name="raid" EOF ``` Regards, -- Nicolas George
