so it's only the rr-cache metadata that is involved? We had a few cases 
where git-rerere sessions were not repeatable by copying the 
.git/rr-cache, so i just assumed that there's some extra metadata in the 
index file. When that happened i took a look at git/builtin-rerere.c:

 static int find_conflict(struct path_list *conflict)
 {
        int i;
        if (read_cache() < 0)
                return error("Could not read index");

and (mistakenly) assumed that git-rerere depends on having something in 
the index file - but on a second look it just checks out the conflicting 
file(s) from the index file, right?
