why is this related to ape? if you are none, then you are limited
as to what you can do on the file server. you may just have an auth problem.

APE implements rename() in terms of wstat or copying. It's just
doesn't try to work around failing wstat (that's perhaps a good thing)
while mv does.
There are no auth problem since I deliberatly run the python web app
as none, not willing to give it eve's powers.

* [9fans] APE rename: wstat for 'none'

Is there a specific reason of forbidding wstat for 'none' in fossil
(/sys/src/cmd/fossil/9p.c:130,133)?
This causes APE rename() to fail almost always
(/sys/src/ape/lib/ap/plan9/rename.c:43)
Perhaps rename() should be fixed to match mv (/sys/src/cmd/mv.c:/^mv1)
to go around this?
