// 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.
