git gc and kernel.org

We have run into two major problems with git on kernel.org. We have discussed workarounds, but I believe they are generally major problems which will affect other sites, and really need to be fixed upstream.

1) git receive-pack doesn't run git gc --auto.

This cause repositories which people thought were being autopacked to not be so. This can be done via a hook, but that is way too painful for people to do -- in fact, it's hard enough just to get people to enable the post-update hook for http fetching.

1b) as per the above, a way to make "git update-server-info" at post-update time a configurable option rather than needing to be done via the hook would be very nice, since a configuration option can be enabled sitewide.

2) When pushing to a repository, it apparently doesn't honor new objects 
in alternate repositories.  This causes massive unnecessary duplication.

I believe these are major issues that need to be addressed. If we are *mistaken* on these, then we would appreciate being corrected.

Thanks,
