Adding fsirand functionality was 5 lines of code in mkfs.c,
less if you don't care about adding fs_id. The real kicker
is what do you do in the kernel when you need a new generation
number? Currently I just increment the already-random gen
number but that's not so hot. You really want something that
preserves the randomness but redoing the random number each
time you create a file seems a bit expensive.
