Custom Partitioning

If your plan is to install Arch Linux on more than one disk or if you don't want to format an entire drive, you have to select NO at Do you wish to install Arch Linux on a dedicated drive? wich will just ask for drive id. This option requires you to create and format partitions before running archboot.

Partitioning scheme:

  SYSTEM_PARTITION......: /mnt            (required)
  BOOT_PARTITION........: /mnt/boot       (required)
  SWAP_PARTITION........: no mountpoint   (optional in custom)
  HOME_PARTITION........: /mnt/home       (optional in custom)

Do not forget, UEFI boot partition requires fat32 filesystem and EFI type. More information on partitioning is available here.
