// 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.
