I don't think so.
However, if you converted to use reserved leases then the clients get
'real' leases which go through the normal lifecycle, appear in the
leases file, and get DNS updates/deletes etc - the only difference
from a normal lease being that a reserved lease will never be
re-allocated to another client. I think you need version 4 for this
functionality, and I don't know how well it's documented. I believe
you need to manually add "reserved" as a keyword in an existing lease
(or create a new skeleton lease with this) to uset he feature - and
of course, that means stopping the server while you edit the leases
file.
