Re: [RFC] FSFS filesystem options (long, sorry)

Correct me if I'm wrong, but Coda never made the jump from research to
production. So I wouldn't let it dictate anything.

It is an example of a filesystem that would become useless in short
order, if the directory size isn't controlled. However, the argument
"get a better filesystem" seems to really apply here :-).

FAT32's 64K entry limitation might be a better example of limits in a
commonly used file system.
