Since in go-git, you can open and clone a repository declaring the kind of fs, I rather having this implementation as an implementation that returns "Not Implemented" errors for every method or one that simply panics if you call to os.New()

// globalMemFs is the global memory fs
var globalMemFs = memfs.New()

const (
defaultDirectoryMode = 0755
defaultCreateMode = 0666

// OS is a filesystem shim for js.
type OS struct{}

// New returns a new OS filesystem.
func New(baseDir string) billy.Filesystem {
return chroot.New(globalMemFs, baseDir)
