The admin_client_skip_domino is a server side notes.ini (although if you apply it to the client it will affect the "Local" server).  I went and tried on 2 10.0FP1 linux boxes and it worked correctly.  If not set, it default to being on. You would have to explicitly set it to 0 to have the Domino directory appear.  A server restart is required when changing it.
