Every filesystem is object-oriented.

You have objects (commonly called inodes, sometimes differentiated as 
files and directories, and some other interesting stuff :), their 
properties (size, ctime, mtime, etc) and allowed methods on them 
(create, read, change, append, delete, ...). You can also define new 
methods on any of them, but it's mostly OS-dependent, rather then 
FS-dependent (so you define a method of "xpdf", and call it on a object 
which contains PDF data).

Oh dear, every Unix is completely object-oriented. What am I to do anymore?

But, of course, there are some things that are really interesting in GNU 
Mach+Hurd approach: you can mostly transparently from userspace override 
things that you had to override explicitely, or from kernelspace. That's 
probably the thing that would make filesystems more "object-oriented" in 
a popular way.

Just my 2eurocents :),
