Basically "executable statements" like conditionals or function calls
that perform an operation (log(), execute(), etc) are only executed
when the "execute_statements_in_scope()" function is called in the
That's only done when the software is trying to source configuration
to return to the client.
Because there is no DHCP protocol answer for a DHCPDISCOVER that the
server cannot currently answer (because it cannot allocate a lease),
it never gets to the point where it wants to determine configuration
image for the client, so the function is never called.
I can't really think of a good workaround.
