Ok, I did

	git repack -A -d

in repo.or.cz's git.git. What next? I have brand-new

	-rw-rw-r-- 1 root root  1314056 2008-09-02 13:07 pack-d19ca8b0cfd0e3357c475a3e96ce55b9f7195667.idx
	-rw-rw-r-- 1 root root 17344999 2008-09-02 13:07 pack-d19ca8b0cfd0e3357c475a3e96ce55b9f7195667.pack

but all the old packs too; git repack didn't delete anything,
git prune-packed seems to have no effect either.

So not just refs but also alternates? What if someone accesses the
reposiory at that moment? I would also need to make the symlinks quite
densely to avoid refs/forkee/-induced loops.

I might as well just use a common repository for all the forks then. But
this does not scale at all for dumb transports, does it?
