Functions

func InitConfManagers

func InitConfManagers()

func Read

func Read() (osrelease map[string]string, err error)

Read and return os-release, trying EtcOsRelease, followed by UsrLibOsRelease. err will contain an error message if neither file exists or failed to parse

func ReadFile

func ReadFile(filename string) (osrelease map[string]string, err error)

Similar to Read(), but takes the name of a file to load instead

func ReadString

func ReadString(content string) (osrelease map[string]string, err error)

ReadString is similar to Read(), but takes a string to load instead

func StartUp

func StartUp(Version string)
