Even before we get Git 1.5.0 installed on master.kernel.org (and we should really ask hpa to do that), is there a reason we haven't done something like this across all of the kernel repo's on master.kernel.org?

for i in <list of kernel git repo's on master.kernel.org>
do
   pushd $i
   if [ ! -f objects/info/alternates ]; then
	echo /pub/scm/linux/kernel/git/torvalds/linux-2.6.git/objects \
	   > objects/info/alternates
	git repack -a -d -l
   fi
   popd
done
