 # Be sure to only define one layout!

-# 1. create_single_disk_layout
-#
-# This layout creates the most common partitioning scheme on a single disk, i.e.
-# one boot, one swap and one root partition. Swap can be disabled and the root
-# partition can be luks encrypted. This is probably the layout you are most familiar with.
-#
-# Parameters:
-#   swap=<size>           Create a swap partition with given size, or no swap
-#                         at all if set to false
-#   type=[efi|bios]       Selects the boot type. Defaults to efi if not given.
-#   luks=[true|false]     Encrypt root partition. Defaults to false if not given.
-#   root_fs=[ext4|btrfs]  Root filesystem
-#create_single_disk_layout swap=8GiB type=efi luks=true root_fs=ext4 /dev/sdX
+function disk_configuration() {
+	create_classic_single_disk_layout swap=8GiB type=efi luks=true root_fs=ext4 /dev/sdX

-# 2. create_raid0_luks_layout
-#
-# This layout creates the single disk layout on multiple disks and combines
-# the swap and root partitions in separate raid0 arrays. Useful if you e.g. have
-# several nvme drives and want greater speed. Only one boot partition will actually
-# be used though.
-#
-# Parameters:
-#   swap=<size>           Create a swap partition with given size for each disk,
-#                         or no swap at all if set to false
-#   type=[efi|bios]       Selects the boot type. Defaults to efi if not given.
-#   root_fs=[ext4|btrfs]  Root filesystem
-# Careful: You will get N times the swap amount, so be sure to divide beforehand.

-# 3. create_btrfs_raid_layout
-#
-# This layout is the same as the single_disk_layout, but uses btrfs as the root
-# filesystem and allows you to put additional disks into the btrfs device pool.
-# Only the first disk will have boot and swap partitions, the other disks will
-# directly be used in the btrfs device pool. If encryption is enabled, all disks
-# must be encrypted separately, as btrfs doesn't support encryption itself.
-# Also works with a single device.
-#
-# Parameters:
-#   swap=<size>                Create a swap partition with given size, or no swap
-#                              at all if set to false
-#   type=[efi|bios]            Selects the boot type. Defaults to efi if not given.
-#   luks=[true|false]          Encrypt root partition and btrfs devices. Defaults
-#                              to false if not given.
