It is just it is not what I expected.  I have been using versions of RedHat 
linux since the (old!) 4.5 release back in the 1990s and adding NFS mounts 
'just worked' without playing any special games.

I've never used the '_netdev' option.  Of course I have not really touched 
RHEL/CentOS 7 (systemd) yet.  All of the RedHat/RHEL/CentOS/Fecora systems I 
have used are all SYSV init systems.
