Here is the function in charge of partitioning the disk from install-image-V2.5.sh:
function partition_RPi4() {
parted --script -a minimal $devicename \
mklabel gpt \
unit MiB \
mkpart primary fat32 2MiB 202MiB \
mkpart primary ext4 202MiB $devicesize"MiB" \
quit
}
I don’t know. I wouldn’t think that it should matter but I can try and report back.
Edit: Not sure if the SSD part still needs to be done manually:
