Thanks for the reply.
I see that 
http://git.kea.isc.org/~tester/kea/doxygen/d8/db2/libdhcp_user_chk.html 
is a start, however it seems a bit much to make a full "plugin" just to 
be able to name the bootfile dynamically based on the options provided 
from the dhcp-client (or relay)

But I will look into it.  It might open up other options that we have 
not thought of yet.
