func NewFromFile added in v0.6.0

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

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

func NewFromMapping added in v0.6.3

func NewFromMapping(workdir, output string, maps ...string) (*InitrdConfig, error)

NewFromMapping accepts a working directory base that represents the relative path of the files to serialize which are provided by a slice of mappings, each delimetered by the default delimeter `:` which separates the path on the host and the path inside of the iniramfs. A destination of the final archive is provided by the positional argument output.

func NewFromPath added in v0.6.0

func NewFromPath(base string, prefix string, files ...string) (*InitrdConfig, error)

NewFromPath accepts a positional argument base which is the directory that the provided files should be serialized from. The prefix positional argument is used to affix all embedded files to the provided location.
