I like the idea of rerere, but have some possible concerns that it might potentially cause some issues with other directories that I don't want to have this enabled on. It would seem that this is an all or nothing thing. Is that correct, or can I set it up for only certain directories?
I'm considering having the rerere cache stored with the repo as given by this script, so need to know about this feature further.
EDIT
If not, would it be possible to enable rerere for the changes I'm interested in and then turn it off again to limit where this is used? If so, in what parts of the process would I do this?
