Subject: [PATCH] libxl: create writable 'error' xenstore dir
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The dir is used by backend hotplug scripts to write error details. When
the backend is in dom0, it implicitly have write access, but the
permission was missing for non-dom0 backends.
