AppendVhdFooter instructs the converter to add a fixed VHD footer to the file.

func Convert

func Convert(r io.Reader, w io.ReadWriteSeeker, options ...Option) error

Convert writes a compact ext4 file system image that contains the files in the input tar stream.

func ConvertWhiteout

func ConvertWhiteout(p *params)

ConvertWhiteout instructs the converter to convert OCI-style whiteouts (beginning with .wh.) to overlay-style whiteouts.
