Folks
I'm playing with a Raspberry Pi 2 and Centos.  Here are some issues 
I've bumped into.  I'm not sure this is the right medium for 
commenting; please correct me if needed.
I wrote a copy of the distributed image (1151) to my MicroSD card, 
then turned on the Rpi2.
Issue 1:
  Even though my DHCP server was configured to give the node a name, 
it showed up as "rpi2" as the host name.
I use:
hostnamectl set-hostname <fqdn>
There are lots of places where hostname is and this controls all of 
them.  Or so I have been told.
...
Issue 2:
  Network works, but if I issue the command
    systemctl reset network
  the command fails and I haven't found a way to get the network 
back.  I saved the output of "journalctl -ce", rebooted, and installed 
"ftp" so I could copy the data to a real machine.  The text is as below.
  I issued the "systemctl reset network" command towards the bottom, 
where you see the time jump from 00:01:01 to 00:02:28
