Find does not work correctly on freefall, some times it only gives
you the top level directory, some times it gives you 2 or 3 levels,
it is as sparodic as ls -R :-(.
Try these on freefall to see what I mean:
cd /cdrom
find .
find .
find .
find /cdrom
find /cdrom
find /cdrom
You'll notice different output depending on what it feels like doing
at that moment. Some of this is very similiar to the problems we once
had in 1.X.

:-(, okay, I was the one who added the fstype isofs to 1.x find, probably
should pull those changes into the 2.x find. Though this is probably not
the problem we are seeing, I suspect that cd9660 is as broken as ever :-(.

Looks like it is time to move my cdrom drive from my old 1.x system over
to one of my 2.x test boxes. I really don't have time to go after this
one, so if you want to track it down and squash it by all means go ahead.
