That's the one to use.  Here is a tutorial for libnetfs:

Why don't you start simpler: work on a *local* repository (that is, one
that has already been cloned, for example)?  I suggest to start by
writing a translator for translating the Git repository (that is, the
content of the .git directory) into a directory / filesystem hierarchy.

Isn't Git implemented in terms of an (internal?) library like libgit (or
similar), these days?  Perhaps you could use that one, too?  Doing so
would greatly simplify the project.


One important task is: how to map the content of the Git repository into
a filesystem hierarchy.
