Linus has "packed" his GIT tree ... and now http-pull doesn't work. 
rsync still does (provided
you have a new enough cogito).

So does that mean we should ignore cogito's whinging about rsync being
deprecated?

Yes, please do. I deprecated rsync a day before Linus "broke" http-pull.
It's un-deprecated again for now in the latest Cogito.

Presumably for packed repos you want to drop the --ignore-existing 
--whole-file options I assume?

Also, pulling with cogito-0.12:

cg-clone -s 
rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git/

I still get:

Is the "missing objects" thing spurious?

It _is_ unsafe for individual objects, and your packfile will be corrupt
if you break it in the middle and not have --whole-file turned on, I
assume. It would be ideal if we could make rsync allow resuming download
of the file if interrupted, but not under the final name but in that
hidden file it uses.

Yes, already fixed. Will release 0.12.1 soon.

I think if you just don't give it --partial you're fine (rsync always 
creates a second copy, --partial decides if a partial file should be 
thrown away or not.)
