  git checkout FETCH_HEAD
  echo "Failed to do a shallow fetch; retrying a full fetch..."
  git fetch origin
  git checkout <commit>

  git submodule update --init --recursive
  rm -rf .git for each submodule
rm -rf .git

See guix/build/git.scm .

There exist git servers that have disabled fetching by commit hash for
"security" reasons (if you checked in a file containing a password and
then removed it again, and no branch or tag to it exists, nobody can
get to it even if he knew the commit hash).  We would always use the
fallback for those servers.

As a fallback if the above doesn't work.
