Some time ago I had problems with the treatment of static leases and
started using the "reserved" statement in the problematical assignment
added to the leases file. . It did take one of the pool addresses up
permanently, but so did the static assignment anyway. For my static
servers, it hasn't caused a problem and it allows whatever
queuing/aliasing to occur naturally. Such a tactic might work for you as
it has to be done on a closed dhcpd anyway. I added the rDNS and also
added the option to turn allow updates off as it failed anyway because it
existed.
