Infini-STICK Setup

Partition Scheme

Position	Label	FS Type	Size	Type
0	`storage`	`exfat`	24.6GB	Generic Storage Partition
1	`vault`	`LUKS/ext4`	3GB	Encrypted Storage Partition
2	`Infini-STICK`	`btrfs`	33.3GB	Root Partition
3	`boot`	`vfat`	511MB	EFI System Partition

Configuration

Setup with a wide array of hardware compatibility, specifically using the portable form defined in the hardware/form module.

Infini-STICK currently lives on my SanDisk 3.2Gen1 64GB USB C/USB A flashdrive.

Script Boilerplate

DISK=$1

sudo mkdir -p /mnt

if mountpoint -q -- "/mnt"; then
    echo "ERROR: /mnt is a mounted filesystem, aborting"
    exit 1
fi

Partitioning

echo "LOG: Partitioning $DISK"
sudo parted $DISK -- mktable gpt
sudo parted $DISK -s -- mkpart primary 0% 100%
sudo parted $DISK -s -- mkpart primary 40% 100%
sudo parted $DISK -s -- mkpart primary btrfs 45% 100%
sudo parted $DISK -s -- mkpart ESP fat32 -512MiB 100%
sudo parted $DISK -s -- set 4 esp on

Making Filesystems

echo "LOG: Making filesystems"
echo "- Making btrfs filesystem on ${DISK}1"
sudo mkfs.btrfs "${DISK}1" -L "Infini-STICK" -f
echo "- Making fat32 filesystem on ${DISK}2"
sudo mkfs.fat -F 32 -n boot "${DISK}2"

Making Subvolumes

echo "LOG: Making subvolumes on ${DISK}1"
sudo mount "${DISK}1" /mnt
sudo btrfs subvolume create /mnt/root
sudo btrfs subvolume create /mnt/root/home
sudo mkdir -p /mnt/root/etc
sudo btrfs subvolume create /mnt/root/etc/nixos
sudo btrfs subvolume create /mnt/boot
sudo btrfs subvolume create /mnt/nix
sudo btrfs subvolume create /mnt/nix/store
sudo umount /mnt

Mounting Volumes

echo "LOG: Mounting tmpfs"
sudo mount -t tmpfs root /mnt

echo "LOG: - Mounting persistent directories"
sudo mkdir -p /mnt/persist /mnt/nix /mnt/boot
sudo mount -o subvol=root,autodefrag,noatime "${DISK}3" /mnt/persist
sudo mount -o subvol=nix,autodefrag,noatime "${DISK}3" /mnt/nix
sudo mount -o subvol=boot,autodefrag,noatime "${DISK}3" /mnt/boot

echo "LOG: - - Mounting persistent subdirectories"
sudo mkdir -p /mnt/home /mnt/etc/ssh
sudo mount --bind /mnt/persist/home /mnt/home
sudo mount --bind /mnt/persist/etc/ssh /mnt/etc/ssh

echo "LOG: - Mounting EFI System Partition"
sudo mkdir -p /mnt/boot/efi
sudo mount "${DISK}4" /mnt/boot/efi

Installing

echo "LOG: Installing NixOS"
sudo nixos-install --flake /etc/nixos#Infini-STICK --no-root-password

Extra (Full Install)

echo "LOG: Cloning configuration"
sudo git clone --no-hardlinks --progress ssh://git@github.com/Infinidoge/universe.git /mnt/persist/etc/nixos
sudo git clone --no-hardlinks --progress https://git@github.com/Infinidoge/universe.git /mnt/persist/etc/nixos-private

Extra (Reinstall)

Finishing Setup

Cleanup

echo "LOG: Unmounting all"
sudo umount -R /mnt
