func Mount(ctx context.Context, basePaths []string, upperdirPath, workdirPath, target string, readonly bool) (err error)
Mount creates an overlay mount with `basePaths` at `target`.
If `upperdirPath != ""` the path will be created. On mount failure the created `upperdirPath` will be automatically cleaned up.
If `workdirPath != ""` the path will be created. On mount failure the created `workdirPath` will be automatically cleaned up.
