Partial sharing of git repositories

Question

I am new to git. I am wondering whether the following scenario is supported, and if so how (i.e. git commands for setup and update).

A repository is available from three different places: 'local', 'mirror' and 'github'. 'mirror' mirrors 'local' completely and 'github' mirrors 'local' except for a 'copyrighted' directory.

Thanks.

Answer 1

A submodule can work, but if you try to clone something that contains submodules for which one of the remotes is unavailable, you'll have aggravating errors.

My alternative would be to use the 'filter-branch' command to maintain a public branch that would omit the copyrighted files for public consumption on GitHub.
