Partition Layout

Describes the standard partition layout required by OCK images.

Installing to a disk with existing partitions requires at least the following partitions:

  • An EFI partition.

  • A boot partition labelled boot.

  • A root partition labelled root.

We recommend the disk contains only these three partitions and that the root partition is the last partition on the disk. The root partition must be last so that the partition can be automatically expanded to fill the entire disk when the OS boots for the first time. Other layouts are possible, but these have limited applicability and require a good understanding of how partitions are laid out and used.
