>
> When the NodeManager tries to initialize the recovery directory, the method
> NativeIO#chmod() can throw one of several Errno style exceptions. This
> propagates up to the top without any try/catch statement.
> It would be nice to have a cleaner error message in this situation (plus the
> original exception) to give users an idea about what part of the system has
> gone wrong.
