Arca Noae’s plan for supporting GPT disk layouts in ArcaOS

Arca Noae’s approach to supporting GPT will be multi-phased, with the first phase of development currently underway and anticipated for release with ArcaOS 5.1. The design specification of our initial GPT support is to allow for partitions up to the current 2TB maximum size, with multiple partitions of this size possible on disks larger than 2TB. Our specification further provides that ArcaOS be able to create, delete, and modify GPT partitions which are identified by their GUIDs as being “OS/2-type” partitions, and lastly, that GPT support be available for both traditional BIOS (for data volumes) and UEFI-based systems (for boot and data volumes).

This is one of the biggest hurdles for ArcaOS to overcome, and I’m glad they’ve committed to tackling it. Having to partition an entire disk in legacy MBR just to be able to run ArcaOS on real hardware is a major barrier to entry.
