		For posterity and others having the same issue, I am updating with research. 
 
I found a thread (in French) in the softpedia forum on this issue. I cannot post the link because I have too few posts in this forum. 
 
It suggests that my OpenNode kernel is too far out-of-date to support the systemd(219) running CentOS 7.2. Hopefully an update will correct that. Will report back.
