Hi Jan,

thanks for the great work!

Still I have some question marks -

the wording seems to be a bit unfortunate.

Does it mean switching to disconnected semantics, something else,
or using unauthenticated connections? I assume you mean the last.

Using unauthenticated connections does not prevent permission denied errors
for protected files, and leads to security weakening for world-readable files
as the unauthenticated connections can be spoofed.
Good as a temporary measure, for conveniency, but IM very HO
it should not survive longer than when we switch to real cryptography,
anyway not as the default behaviour.

I guess it is not worse than otherwise - as we did not follow Unix
traditions about dirlinks anyway.
Still, I think the culprit has always been gnu find, -noleaf should have been
the default mode, not vice versa.
There are many other filesystems which in one or another way differ from
"exact optimizeable dirlink behaviour" - like dirlink count wrapping over 2^16.
Now it is filesystems who are adapting themselves to gnu find... a bit odd :)

That's great.

Again, thanks.
