Say that I have a repository at /some/dir, and a tree that contains most of its files at /another/dir (the second is a build directory, made with `git archive', so some files removed due to export-ignore attributes and some built files are present).

Is there a convenient way to make /some/dir usable as a repository? Two things that I tried are

  git --work-tree=/another/dir reset --hard master

which one time, but then failed with "fatal: unable to read tree...", and another is

  cp -a /some/dir/.git /another/dir
  cd /another/dir
  git reset --hard master

which looks like it can suffer from the same problem.

(It would be especially nice if there's a way to have only different files touched in /another/dir.)
