#26 — Confusing failure "Is a directory" at root of FS Mount

This happens with svn trunk and 1.1.0b1, on Plone3 / Zope 2.10 - if 1.1.0b1 is patched to import CMFCore.permission as CMFCorePermission in a couple of files, which may be the only change to trunk - I haven't checked.

Essentially, the render fails with an "Is a directory" error from a call to open('...','w') in CMFDeployment.segments.storage.ContentStorageManager.storeDescriptor. Maybe something slightly different at the root, or with containers in general, from Plone2 to Plone3 has caused this? I wouldn't expect the code to be designed to open() a directory. :)

Here's the tasty tb - actually, the entire zope log output from the running of this profile:

In the steps, I have a couple of notes just to make sure that if something in the zmi or otherwise, or the default behaviour, changes drastically, it may be clear to you without strapping up a test rig yourself.
