Re: Efficient way to import snapshots?

Yes, although I think you need to do "git commit -a" for that. 

"git add ." could (and perhaps _should_) notice them and remove them from the cache, but doesn't. Whether that's the right behaviour or not (it does seem a bit strange that "git add" would actually remove files from the index too) is up for debate.

But with "git commit -a", it will be noticed at commit time, at least.

That said, I just noticed something nasty: "git add ." is *horrible*. It does the full SHA1 re-computation even though the index is up-to-date. That's really nasty.

So right now, due to this performance bug, it's actually much better to do something more complex, namely something like

	git ls-files -o | git update-index --add --stdin
	git commit -a

which is a lot more efficient than just doing "git add .".

Junio? I _thought_ we already took the index into account with "git add", but we obviously don't.

Whatever branch is checked out in the GIT_DIR will be the one that it commits to.
