Repacking the fedora-web git repo for better cloning performance

[Todd Zullinger]

Hi all,

I was talking with Sijis in IRC about ways to help improve clone times
for the git repo.  Looking at the repo on hosted, it could really
benefit from a git repack.  This takes all the loose object files and
puts them neatly into .pack files.  It also optimizing them based on
how they change from commit to commit.

I did this on a copy and shrank the git repo from 431M to 225M (this
excludes the size of the checked out files -- it's basically the size
of the .git dir in a clone).

I could do this on the official repo if we wanted.  It would mean
disabling the repo for a short time (half an hour at most).  Anyone
see a reason not to do this?

Nick reminded me that I still need to do this.  I'm going to do it
now.  If you notice the web repo is down for a short time, this is
why.  I'll send afollow-up when it is completed.

This is completed.  The size of the git repo shrunk from 504M to 242M.
A fresh checkout now takes up a mere 354M.

Please yell if you run into any trouble cloning or pushing.
