I've run dnsmasq for several years on my small home LAN.  I'm running
dnsmasq on a raspberry-pi and most of the client machines on the LAN
are linux (xubuntu).

I've suddenly lost the ability to resolve local machine names without
a domain suffix, e.g.:-

    On the Raspberry Pi itself:-

    chris@newdns$ host esprimo
    Host esprimo not found: 3(NXDOMAIN)
    chris@newdns$ host esprimo.zbmc.eu
    esprimo.zbmc.eu has address 192.168.1.3
    chris@newdns$ 

... and on a Linux machine on the LAN:-

    chris$ host t470
    Host t470 not found: 2(SERVFAIL)
    chris$ host t470.zbmc.eu
    t470.zbmc.eu has address 192.168.1.92
    chris$ 


So what's gone wrong/changed?  The raspberry pi is pretty up to date:-

    chris@newdns$ uname -a
    Linux newdns 4.19.66-v7+ #1253 SMP Thu Aug 15 11:49:46 BST 2019 armv7l 
GNU/Linux
    chris@newdns$ more /etc/issue
    Raspbian GNU/Linux 9 \n \l
    chris@newdns$ dnsmasq --version
    Dnsmasq version 2.76  Copyright (c) 2000-2016 Simon Kelley

I don't *think* I've changed anything in /etc/dnsmasq.conf recently.

Help!! :-)
