func NewFromFile

func NewFromFile(path string) (*InitrdConfig, error)

NewFromFile interprets a given path as a initramfs disk file and returns an instantiated InitrdConfig if successful.

func ParseInitrdConfig

func ParseInitrdConfig(workdir string, value string) (*InitrdConfig, error)

ParseInitrdConfig parse short syntax for architecture configuration

func (*InitrdConfig) NewReader

func (i *InitrdConfig) NewReader(w io.Reader) (*cpio.Reader, error)

func (*InitrdConfig) NewWriter

func (i *InitrdConfig) NewWriter(w io.Writer) (*cpio.Writer, error)
