> 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.
