Nice, I built something similar ~5 years ago using nested git repos and scripts to accomplish a similar purpose of combined private and public repos.

My shell script definitely wasn't google scale tho!

Yep, same. I thought it might a wrapper around git subtree but looks like it’s doing quite a lot more!

For example altering commit author emails during sync

Cute name. (Naming is hard and important.)

Some other interesting tools in the space. Rust is using a tool called Josh to sync commits:

https://josh-project.dev

The blog post from the Rust people:

Meta used to have an open source tool called fbshipit. But according to its open source repo they no longer use it:

Any others in this space?
