+# Legacy site-local option support
+# If client does not include an etherboot-encapsulated-options field in its DHCPREQUEST, then
+# it will not understand etherboot-encapsulated-options in the DHCPACK and so we must send
+# back the options as site-local options (i.e. not encapsulated).
+# Note: we need do this only for options that existed prior to the switch to encapsulation.
+#
+# For some reason the encapsulation option makes isc-dhcpd-V3.0.1rc11
+# crash (too much info encapsulated?).
