Bug#803912: partman-efi should follow partman-auto/disk to reuse the ESP.
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.
