# Disk configuration

# This function will be called when the key for a luks device is needed.
# Parameters:
#	$1 will be the id of the luks device as given in `create_luks new_id=<id> ...`.
# Example: Keyfile
#   1. Generate a 512-bit (or anything < 8MiB) keyfile with
#      `dd if=/dev/urandom bs=1024 count=1 of=/path/to/keyfile`
#   2. Copy the keyfile somewhere safe, but don't delete the original,
#      which we will use in the live environment.
#   3. Use `echo -n /path/to/keyfile` below.
# Example: GPG Smartcard
#   Same as above, but do not store a copy of the keyfile and instead store a
#   gpg encrypted copy: `cat /path/to/keyfile | gpg --symmetric --cipher-algo AES256 --s2k-digest-algo SHA512 --output /my/permanent/storage/luks-key.gpg`
luks_getkeyfile() {
	case "$1" in
		#'my_luks_partition') echo -n '/path/to/my_luks_partition_keyfile' ;;
		*) echo -n "/path/to/luks-keyfile" ;;
	esac

# Below you can see examples of how to use the two provided default schemes.
# See the respective functions in internal_config.sh if you
# want to use a different disk configuration.

# Create default scheme (efi/boot, (optional swap), root)
# To disable swap, set swap=false
# To disable encryted root, set luks=false
#create_default_disk_layout luks=true root_fs=btrfs swap=8GiB /dev/sdX            # EFI
#create_default_disk_layout luks=true root_fs=btrfs swap=8GiB type=bios /dev/sdX  # BIOS
#create_default_disk_layout swap=8GiB /dev/sdX

# Create default scheme from above on each given device,
# but create two raid0s for all swap partitions and all root partitions
# respectively. Create luks on the root raid.
# Hint: You will get N times the swap amount, so be sure to divide beforehand.
#create_raid0_luks_layout swap=4GiB /dev/sd{X,Y}             # EFI
#create_raid0_luks_layout swap=4GiB type=bios /dev/sd{X,Y}   # BIOS
#create_raid0_luks_layout swap=false type=bios /dev/sd{X,Y}  # BIOS no swap

# Create default scheme from above on first given device,
# encrypt and use the root partition of this first disk plus
# encrypt and use the rest of the devices to create a btrfs raid
# array of specified type. By default is uses striping. Specify
# raid_type=mirror for raid1.
# Hint: Swap will only be on the first disk.
create_btrfs_raid_layout swap=8GiB luks=true /dev/sd{X,Y}                    # EFI
#create_btrfs_raid_layout swap=8GiB type=bios luks=true /dev/sd{X,Y}         # BIOS
#create_btrfs_raid_layout swap=false type=bios raid_type=mirror /dev/sd{X,Y} # BIOS, raid1, no luks, no swap
