Eu atualizei meu rPi2 de Wheezy para Jessie ... ele inicializa e parece OK, exceto que o dnsmasq falha após a inicialização com:
sudo service dnsmasq status

Eu posso iniciar o dnsmasq com o sudo dnsmasq e ele funciona. (Bacground: Estou usando o serviço isc-DHCP; e mais tarde solicitei um proxy DNS, quando instalei o dnsmasq.)
Alguma ideia de onde procurar?
A configuração é:
grep -E -v '(^$)|(^#)' /etc/dnsmasq.conf
domain-needed
bogus-priv
local=/localnet.beta.net/
server=180.181.12.3
server=180.181.12.4
interface=eth0
listen-address=127.0.0.1
no-dhcp-interface=
expand-hosts
domain=alpha.org
Desculpas ... esta questão pode ser removida ... já que não executo mais o dnsmasq. Eu tenho, por frustração e a ideia de uma solução melhor, instalei bind9. Juntamente com o isc-dhcp, ele agora tem uma funcionalidade maior do que o dnsmasq poderia oferecer ... e está funcionando :) Obrigado.
