I do not think Peter meant to "git add .git/config && git commit" by
referring to the 'could not commit config file' error message he
saw; you two are going in a wrong direction.

    $ git grep 'could not commit'
    config.c: error("could not commit config file %s", config_filename);

I do share Fredrik's suspicion that the virtual filesystem the
Ubuntu guest is trying to write to is at fault, but I never used
"vagrant shared", and I do not know in what specific way their
filesystem is not behaving as we expect.

Applying 7a64592c (config.c: fix writing config files on Windows
network shares, 2015-06-30) might be an interesting thing to try.
Some filesystems do not want to rename a file that has mmaped region
still active, which is my blind guess.
