I have a question about remotes behavior on external drives.

Say I have two machines A and B each with a git annex repository at ~/repo, and an external drive C with the same repository at /repo.

I can add C remotes for A and B at, for example, /media/hdd/repo, but I'm not certain how it works for C.

Do I stick C into A and add a remote A at path ~/repo, then stick C into B and add a remote B with the same path ~/repo? Does git annex handle this sanely?
