SQL Server 2014 - Add Node inherits wrong configuration I'm setting up a simple 2-node failover cluster with SQL 2014 on Server 2012 R2 in Core mode (no GUI). I have the cluster configured with identical machines, and I have the first node configured and working. 

When I go to add the second node however, the wrong configuration information is used. Specifically, the shared and instance binary locations point to the OS drive (I installed them on a different drive on node 1). I tried manually specifying the locations in the configuration file, but setup won't accept these parameters when the install mode is AddNode. Did I do something wrong, or is this a bug?
It appears to be a bug/feature. It was discussed previously on SQL Server Central http://www.sqlservercentral.com/Forums/Topic1578488-2799-1.aspx where Ed Vassie said:


  Put it another way... On an ADDNODE install you cannot specify the
  location for the SQL binaries, they always go to the system drive.
