Lena Setup Specifics

Machine: Lenovo Ideapad 5 2-in-1 (Ryzen 7 8845HS)

1. Disk Partitioning (Btrfs)

Lena uses a Btrfs subvolume layout with ZSTD compression. Use these steps in the installer:

Step 1: Subvolume Creation

# Mount the main partition (nvme0n1p3)
mount /dev/nvme0n1p3 /mnt

# Create subvolumes
btrfs subvolume create /mnt/@
btrfs subvolume create /mnt/@home
btrfs subvolume create /mnt/@nix
btrfs subvolume create /mnt/@log

umount /mnt

Step 2: Mount with Optimizations

# Mount Root
mount -o subvol=@,compress=zstd,noatime /dev/nvme0n1p3 /mnt

# Create mount points
mkdir -p /mnt/{home,nix,var/log,boot}

# Mount others
mount -o subvol=@home,compress=zstd,noatime /dev/nvme0n1p3 /mnt/home
mount -o subvol=@nix,compress=zstd,noatime /dev/nvme0n1p3 /mnt/nix
mount -o subvol=@log,compress=zstd,noatime /dev/nvme0n1p3 /mnt/var/log

# Mount EFI (nvme0n1p1)
mount /dev/nvme0n1p1 /mnt/boot
