.git inside a .git: is it safe?

Hi,

I'm actually working on the packaging of a project. To do so, I use
two Git repositories:
- one to follow the main project
- one to manage my updates on this project.

But, the matter is I cannot merge the both root. I need to have the main project sources in a subdirectory of my own project. My workspace is as follow: myproject/sub/tree/mainproject

With SVN, I think such things are handled with svn:external.

Actually, with Git, I frequently copy the mainproject inside its subtree in my workspace.

But, I recently discover that everything seems fine if I include the
Git repo of mainproject inside the Git repo of my project. The layout
lloks like this:
myproject
|- .git
|- sub
  |- tree
    |- mainproject
      |- .git

It seems to work. But do you think such layout is "safe" ?

Yes, that's fine. You just probably want an entry in the top level project (myproject) that says ignore the stuff under mainproject. That way "git add ." in myproject doesn't include files in mainproject by accident.

Thanks for your answers. It's really a cool feature for my needs.

In fact, in my case, I think I will prefer to store the mainproject's sources in both Git repo. By this way, I will be able to easily found the version of mainproject's sources that are compatible with the rest of myproject.

IIRC Junio uses similar layout managing todo branch in git.git (which comes from separate repository).
