Re: [9fans] Do we have a catalog of 9P servers?

[Charles Forsyth]

NFS4 still assumes that a file handle can be used to
find a file; neither the persistent nor the volatile
variants are directly comparable to a Qid and both can
complicate implementation.  (at least a volatile file handle
allows a file system implementation not based on inodes to be
done more easily than previously.) 9P uses fids instead,
which aren't coupled to Qids, with a lifetime limited
to at most a single session (and more usually they are explicitly clunked).
