As another way to do it, I've used something along the lines from
    http://article.gmane.org/gmane.comp.version-control.git/62062
namely:

<script>
gitdir=$(git rev-parse --git-dir)
[ -n "$gitdir" ] || die "cannot find Git directory"

cd "$gitdir"
a=objects/info/alternates
if [ -f $a ]; then
  git rev-parse --all HEAD | git pack-objects --revs objects/pack/pack
  rm $a
fi
</script>

I was not sure HEAD would be included via --all (e.g. HEAD pointing to a 
dangling commit), so I added it explicitly.

The reverse operation (enabling sharing for a standalone repository) is 
described here
