I have installed and configured dhcpd to function as a mainly
static bootp. Just to test it's dynamic-bootp function I also
configured two machines without static addresses and defined
a space of two ip's which could be allocated to these three
hardware-addresses.
I have also defined the flag
boot-unknown-clients false;
at the top of /etc/dhcpd.conf right after server-identifier.

Unluckily every now and then some client whose address is not
listed in /etc/dhcpd.conf is assigned one of the dynamic-ip-addresses
causing an address-request from one of the two above clients to
fail (when they are eventually used). 

When I look at the debug-output I discover that the requests are
noticed with: Ignoring unknown BOOTP client ....
but if it has a free address it says: BOOTREPLY on 134.155.59.58
(one of the free addresses)
Why is dhcpd ignoring the boot-unknown-clients false; flag ?
