Dear diary, on Thu, Apr 28, 2005 at 04:47:24AM CEST, I got a letter where Daniel Barkalow <barkalow@iabervon.org> told me that...

Just do cg-pull barkalow, to get the latest changes from that repository (perhaps clone should inherit branches information?).

But if you want Linus to pull from your tree, you generally want it to be clean - that is, you want to manage clean separation (as Pavel Machek describes in his document). That is another advantage of hardlinking - you don't get any unrelated stuff in if you don't explicitly pull it, so you can keep your for-linus branch clean. I'd do cg-diff linus:this in the barkalow branch instead to keep this property.
