Hi,

 can somebody help to gather the desired informations? Since I'm not
able to reproduce our problem i cannot answer Simons questions:

>> The above mechanism is working fine in most cases. But lately there were
>> a few reports (4 afaik) that this mechanism is not working entirely
>> reliable.
>> Dnsmasq re-reads it's configs but still claims that no address is
>> available for the specific mac-address, while other clients are still
>> receiving their adresses fine.
>> The new entries in hostsfile do not get served until dnsmasq is killed
>> and restarted.
> ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
> This might be significant, since the process on re-read a hostfile is
> 
> 1) Throw away all entries which came from a hostsfile in the past.
> 2) Read the hostsfile and insert all the entries found there.
> 
> It's difficult to see how that process could distinguish between new and old entries except if some hosts already have leases. Can you Explore this a bit more? Maybe release a DHCP lease on an old host, and then see if it can get a lease back again?

and...
