-Eliminate a lot of output (debug and expected error messages)
-Properly failover to all dhcpservers for getdestiny, nextdestiny, and getipmi
-Randomly vary some sleep intervals to self-segregate nodes in time to take it easy on xCATd
-Enhance x86 architecture detection to differentiate x86_64 and x86 with an x86 kernel
-Only down nics during discovery if the broadcast domains conflict
