Package: partman-efi Severity: normal Dear Maintainer,
Current implementation in partman-efi/fstab.d/efi is to find the first EFI System Partition (abbr. ESP) to use when we provided some kind of partman-auto/expert_recipe. However if the system has more than two ESPs, partman-efi will still use the first ESP it found even when we specify what we want in partman-auto/disk. For example, when the system has /dev/nvme0n1 and /dev/sda and we specified partman-auto/disk and partman-auto/expert_recipe as the following. d-i partman-auto/disk string /dev/sda d-i partman-auto/expert_recipe string \ \ debian :: \ 100 150 200 free \ $iflabel{ gpt } \ $reusemethod{ } \ method{ efi } \ format{ } . \ \ 500 10000 4000000 ext4 \ $primary{ } \ method{ format } \ format{ } \ use_filesystem{ } \ filesystem{ ext4 } \ mountpoint{ / } . \ \ 105% 150% 200% linux-swap \ method{ swap } \ format{ } \ . If there is already another Linux system installed in /dev/nvme0n1, partman-efi will reuse /dev/nvme0n1p1 and mount it at /target/boot/efi instead of reusing /dev/sda1 that we specify in partman-auto/disk. This should not be the behavior that we expected it will be.
