The idea was to push from all of my repositories into a super repository

[[ -d "$SUPER" ]] || \

  git --git-dir="$i" push -f "$SUPER" "*:refs/$name/*"

git --git-dir="$SUPER" gc --aggressive

for i in $PROJECTS/*/.git; do
  git --git-dir="$i" repack -Ad #unnecessary?
  git --git-dir="$i" gc --aggressive

I see, when multiple projects share the same objects, you push them into those 
projects independently first, and the script will later move them to $SUPER.

Clearly I can lose data if I try to rebase $SUPER or something, but I think
it's pretty safe for normal use.

It looks safe unless somebody messes with $SUPER.  A lot of repacking will 
still occur as part of moving stuff to $SUPER, though.

I was trying to set things up so that this extra work won't be necessary in 
the first place.

Thanks!
