[libvirt] Repack git repo?

[Michal Privoznik]

So I was checking out the repo the other day and it took ages. So it got
me thinking what might be the problem. Looks like a part of it is that
our pack is split among ~250 files. Therefore when somebody does
checkout git needs to repack it into a single pack every time. And this
may take ages on such slow processor as Atom is. However, reading some
docs on this it looks like 'git gc --aggressive' is not advised rather
than 'git repack'.

Any thoughts?
