I know that iOS has two partitions, but I've never found anywhere that gives clues as to where they split. Is one partition on `/` and the other on `/var/mobile/`, or are all the user profiles (`/var/root/`, `/var/wireless/`, etc) on the second partition (at `/var`)? Is it possible to resize these partitions? On the same note, is `/var` a symbolic link to `/private/var/` or is it the other way around?
