     I found the problem.  It was not a distro issue.  It was my error.  
Before I wiped the OS, there was some sort of fatal error going on.  For 
testing purposes, I disabled IPv6 in the /etc/defaults/isc-dhcp-server 
file, but I accidentally neglected to comment out the INTERFACESv6 
line.  This was causing dhcpd to issue an exit code of 1.  This not only 
caused the start option to report an error, but also was preventing the 
stop option from cleaning up the .pid file and terminating the daemon.  
Before wiping the OS, I copied all the config files to a backup and 
restored them after the re-install.  This cleared whatever was causing 
the fatal issue, but retained the spurious error report.
