Drive is 4TB, may be it is too big ...

I get into reformatting by hand using "GPT" instead of "MBR"

# Remplacez /dev/sdc par votre disque réel
export DISK=/dev/sdc

# 1. Créer la table GPT
sudo parted -s $DISK mklabel gpt

# 2. Partition BOOT (8 Go - SkiffOS standard)
sudo parted -s $DISK mkpart "boot" fat32 1MiB 8GiB
sudo mkfs.vfat -F 32 -n "boot" ${DISK}1

# 3. Partition ROOTFS (2 Go)
sudo parted -s $DISK mkpart "rootfs" ext4 8GiB 10GiB
sudo mkfs.ext4 -L "rootfs" ${DISK}2

# 4. Partition PERSIST (Btrfs - Tout le reste)
sudo parted -s $DISK mkpart "persist" btrfs 100%
sudo mkfs.btrfs -L "persist" ${DISK}3

sudo make cmd/pi/common/install worked..

but i got a boot kernel panic

Thanks for testing. Hmm, I think I will change pi5 to use the squashfs boot instead of ramfs boot. Will fix today and let you know.

Just to confirm - you read through both the format and install scripts to verify that all of the necessary files were copied? Could you try with a smaller SD card like 64 GB first just to see if it works that way?

Yes, following README, it is working on 64GB microSD card

I will change pi5 to use the squashfs boot instead of ramfs boot.

kernel panic was about that...

in my opinion, it is is also interesting to use btrfs instead of ext4 as "persist" partition

4TB is a lot bigger than the drives i've checked. if you can get it working, please let me know how and i'll integrate the changes into this repo
