It sort of does.  See the dhcp-options(5) man page, search for "SETTING
OPTION VALUES USING EXPRESSIONS", then see the dhcp-eval(5) man page,
then guess that something like one of the following might work:

	option dhcp-client-identifier = substring(hardware,1,6);
	option dhcp-client-identifier = binary-to-ascii(16, 8, ":",
					substring(hardware,1,6);

(The next step, fixing whatever dumb mistakes I have made above, is left
as an exercise for the reader.  I personally use a constant string as my
dhcp-client-identifier.)
