Solution to my own problem (hacked together) use if looks good to

Samba doesn't handle that at the moment. To handle it properly would
be quite tricky because all the netbios names would need to be
un-registred then re-registered with the new address. 

hmmm, could we even un-register properly? A secure WINS server will
reject the un-register from the new IP (or at least will time out
waiting for a confirmation from the old IP) and we can't register our
new names until the old ones are un-registered. Messy.

If Samba got a 10 second warning then it would be easier, but still
tricky. I think this sort of functionality is sufficiently rarely
needed and tricky enough that we just put it in the too hard
basket. Stopping/starting all network daemons makes more sense.

if you leave out the interfaces line completely then Samba will try to
query the OS to find the primary interface, netmask etc. 

If you use a interfaces line then you need to give full info.

use a WINS server (Samba can do that for you), that way broadcasts
don't matter nearly so much.

if you leave off the mask then Samba will use a default mask (the
class mask). You could consider this a bug, Samba should really call
the code that works out a mask given IP by querying the OS on a raw
socket.

right now it does look for date changes in the config files and
reloads many things, but it doesn't do a total reload. The internal
structures of Samba make it hard to do a total reload (think about
live connections, open sockets etc).
