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
DHCP software.
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.
