you can also setup a local remote which hardlinks the index so it doesn't occupy more space. Why? Idk. You don't want to share stash, rerere-cache, branches whatever.

Also handy if you're running an agent in a container on the local fs. Set up a local clone, contain the agent to that repo folder and have it hack away on that. Later, you step out of the container and do the syncing. You can't use worktrees in this situations.

Bare repos are also pretty cool. You can clone the git mailing list as a bare repo and search for threads there instead of setting up an mbox (same for the kernel obviously)
