Constants

const (
	// BootA is a syslinux label.
	BootA = "boot-a"

	// BootB is a syslinux label.
	BootB = "boot-b"

	// SyslinuxLdlinux is the path to ldlinux.sys.
	SyslinuxLdlinux = constants.BootMountPoint + "/syslinux/ldlinux.sys"

	// SyslinuxConfig is the path to the Syslinux config.
	SyslinuxConfig = constants.BootMountPoint + "/syslinux/syslinux.cfg"
)

Functions

func Default

func Default(label string) (err error)

Default sets the default syslinx label.

nolint: gocyclo

func Install

func Install(fallback string, config interface{}, sequence runtime.Sequence, bootPartitionFound bool) (err error)

Install implements the Bootloader interface. It sets up syslinux with the specified kernel parameters.

nolint: gocyclo

func Labels

func Labels() (current, next string, err error)

Labels parses the syslinux config and returns the current active label, and what should be the next label.

func Prepare

func Prepare(dev string) (err error)

Prepare implements the Bootloader interface. It works by writing gptmbr.bin to a block device.

Types

type Cfg

type Cfg struct {
	Default string
	Labels  []*Label
}

Cfg reprsents the cfg file.

type Label

type Label struct {
	Root   string
	Kernel string
	Initrd string
	Append string
}

Label reprsents a label in the cfg file.

type Syslinux

type Syslinux struct{}

Syslinux represents the syslinux bootloader.
