Sharing repositories later on

Sharing repositories later on

[Erik Mouw]

Hi,

I just learned out about "git clone -s" to share objects between
repositories. How do I use that with already existing repositories?

Right now I have a "linux-2.6" repository to track Linus's 2.6 kernel
tree and an "elinux-2.6" tree that pulls from linux-2.6 and holds my
own changes. I created a file .git/objects/info/alternates that
contains the line "/home/erik/git/linux-2.6/.git/objects". Now how do I
get rid of the "old" objects and packs without loosing my changes?

repack -a -d -l perhaps?

Do

	echo "/source/git/project/.git/objects/" > .git/objects/info/alternates

and then follow it up with

	git repack -a -d -l

where the "-l" means that it will only put _local_ objects in the 
pack-file (strictly speaking, it will put any loose objects from the 
alternate tree too, so you'll have a fully packed archive, but it won't 
duplicate objects that are already packed in the alternate tree).

Thanks, that did the trick. I now have a small pack with around 100
objects.
