opcode from Ganeti. This lead to incompatible changes in the format of
the JSON file. It's now not a custom dict anymore but a dict
compatible with the ``OpInstanceCreate`` opcode.
+- Parent directories for file storage need now to be listed in
+ ``$sysconfdir/ganeti/file-storage-paths``. ``cfgupgrade`` will write
+ the file automatically based on old configuration values, but it can
+ not distribute it across all nodes and the file contents should be
+ verified. Use ``gnt-cluster copyfile
+ $sysconfdir/ganeti/file-storage-paths`` once the cluster has been
+ upgraded. The reason for requiring this list of paths now is that
+ before it would have been possible to inject new paths via RPC,
+ allowing files to be created in arbitrary locations. The RPC protocol
+ is protected using SSL/X.509 certificates, but as a design principle
+ Ganeti does not permit arbitrary paths to be passed.
