Manually turning a --bare local repository to a real mirror repository (--bare --mirror)

Hi,

I'm setting up a local git repo which should mirrors the branches of the original repo and at the same time hosts the local private developement branches of the team.

At first step I did create a local copy by issuing:

git clone --bare <original_git_repository>

I found out later that fetching the various refs lead the local master ref not automatically following the remote/master ref, after every git fetch --all. I found that I have to use:

git clone --bare --mirror <original_git_repository>

instead to get that effect. Now please keep in mind that I intend to also create local private branches where developers will push their custom code.

My question: given that I don't have enough bandwidth and constant Internet connectivity, I'd like to ask if it's possible to manually turn a pure --bare local repository into a --bare --mirror one? If yes, how to do that?

Please CC me when replying, because I'm not registered to the mailing list.

Thanks,
