I've read various things about git's rerere feature, and I'm considering enabling it.

The git rerere functionality is a bit of a hidden feature. The name stands for “reuse recorded resolution” and, as the name implies, it allows you to ask Git to remember how you’ve resolved a hunk conflict so that the next time it sees the same conflict, Git can resolve it for you automatically.

But I haven't seen anyone mention any possible problems that could arise while using rerere.

I have to assume there is a downside, or it would probably be enabled by default. So is there any downside to enabling rerere? What potential problems can it cause that would not otherwise occur?

git merge git-rerere
