My server is named ltsp.winonacotter.org and the /etc/hosts named all workstations as
wsXXX.ltsp.  So I assume it automatically uses whatever the machine name is that is
assigned in setup and not the domain.  My guess is that if I called this
supernova.winonacotter.org my /etc/hosts would have wsXXX.supernova.  But I cannot
verify this either as I have always named the machine ltsp in my setups.
