| // Zircon sysconfig partition format |
| // |
| // The sysconfig partition consists of four kvstore sections, each 32K in size. |
| // The sections are: |
| // |
| // version-a: System configuration used when booting from Zircon-A. |
| // |
| // version-b: System configuration used when booting from Zircon-B. |
| // |
| // boot-default: Default bootloader configuration. |
| // |
| // boot-oneshot: Bootloader configuration for one-time use. |
| // If present, this overrides boot-default, and the bootloader |
| // deletes this section after use. |
