Often in CTFs, we may need to create 2 overlapping fake file structures and link them with the ->chain field.
The current implementation of the FileStructure class in pwntools is excellent for a single file struct, but it becomes difficult when we have overlapping structs.
Hence, it would be good if pwntools provided an automatic way to merge/overlap two FileStructure objects.
I believe I can implement this and would open a PR shortly
