Thanks for your reply Randy.

Further browsing through Droms and Lemon showed how to create them:

set variable-name = value;

and it's possible to prevent them being stored in leases by unsetting 
them when they've done their job:

unset variable-name;

I also found mention of them in the dhcpd.leases(5) man page:

        set variable = value;

        The  set statement sets the value of a variable on the lease.  For gen-
        eral information on variables, see the dhcp-eval(5) manual page.

However, its promise of more information in the dhcpd-eval(5) man 
page was hollow--there's nothing about them there at all.
