Simon,
I tried adding the dhcp-ignore-names  option as you suggested, but it didn't 
make a difference.
Running dhcpcd -Td eth0 doesn't print any suggested hostnames from dnsmasq, 
unless I tell the client to not send a hostname.

Is it desired behaviour to only send the client a hostname under certain 
conditions?  It would really help me out if it always sent it, and then let 
the client decide what to do with it.
