jj git clone --reference (or passing arbitrary flags to git)

[sliedes]

I'm cloning a massive repository over the network, for which I have another identical or almost identical clone on my local disk. Git allows me to fetch objects from the other local clone when available:

git clone [email protected]:NixOS/nixpkgs.git --reference ~/proj/nixpkgs

(There's also --shared which is different in that it only hardlinks the objects instead of copying.)

Is this somehow achievable using jj git clone? Is there a way to pass arbitrary flags to the git clone, for example? The best I could come up with does a regular git clone and then change that into a colocated repository. Maybe that's the recommended way, but I don't quite get if it's exactly equivalent to a jj git clone.

Not that's currently not possible, but it may be possible if we get a jj git run command which shells out to specific Git commands.

The only additional thing I'm aware of that jj git clone does is setting the trunk() alias to whatever the upsteam's default bookmark is.

Nixpkgs uses master which is included in the default value, so there's no difference for your use case.
