(I'm assuming that you mean the Coda server when you write Coda,
but then, what is the name of the userland client ?)

What I was really intressed to know is how you from a fid get to
file on the disk ie:

fid (1,2,3) 
   --> Inode-foo (InodeParams = (part = 1, volume = 1, file = 2) ...) 
   --> /vicepa/1/1 

Is this right ? And where do you map the acl (which is at directory level ?)
for the file.

Yes. A bit, Thank you.
