Yes, people have built fuzzers for filesystem images (there are even more if you mean things like syscalls - see fsx, trinity, syzkaller etc). Several years ago an Oracle developer applied afl to a number of different filesystem images and found bugs could be triggered within a few minutes of fuzing (but I don't know if the code for this was ever released). Going back further, the month of kernel bugs introduced the fsfuzzer back in 2006.
