I thought I had a simple (if inconvenient) work around but it looks like 
something (either the deploy or syncing the management network) puts the 
HWADDR line back in ifcfg-em1_1.  I'm going to do some more testing...  
Yep, it's the network sync that adds HWADDR back which then triggers 
udev to rename em1_1.538 to em1_1 which doesn't work and I end up with 
"rename??@em1_1".  I can live without the sync I suppose.  I'll try 
leaving the manual config of the management network alone and then 
config the other networks and see what happens.
