I noticed that when experimenting, so I removed the dynamic lease before
doing more tests. So this isn't the source of the problem I see.

Sure, I could do that. But that would mean considerable extra work for
every computer I want to hook up to my home network, when in theory one
extra line in /etc/ethers should achieve something similar. I can work
around the problem I see, sure, but I'd prefer a bug fix.

All I'm asking is if what I'm seeing is expected behaviour. There's
little point in upgrading if there's no bug to fix.
