I just tried again. This is what I get:

Sat Oct  1 22:46:44 2016 daemon.err dnsmasq[2705]: failed to load names from /etc/hosts: Permission denied
Sat Oct  1 22:46:44 2016 daemon.info dnsmasq[2705]: read /tmp/hosts/dhcp - 4 addresses
Sat Oct  1 22:46:44 2016 daemon.info dnsmasq[2705]: read /tmp/hosts/odhcpd - 0 addresses
Sat Oct  1 22:46:44 2016 daemon.err dnsmasq-dhcp[2705]: failed to read /etc/ethers: Permission denied

The weird thing is, the permissions on these files:

# ls -l /etc/hosts /etc/ethers
-rw-r--r--    1 root     root             0 Oct  1 19:18 /etc/ethers
-rw-r-----    1 root     root           110 Oct  1 19:18 /etc/hosts

and

# ls -l /rom/etc/hosts /rom/etc/ethers
ls: /rom/etc/ethers: No such file or directory
-rw-r-----    1 root     root           110 Oct  1 19:18 /rom/etc/hosts

I can understand the reason why /etc/hosts is not readable, dnsmasq is running as dnsmasq:dnsmasq and so is unable to read it. But what I don't understand is, why /etc/ethers can't be read. According to the permissions, it should be readable by dnsmasq. Even after rebooting, it can't be read. So either dnsmasq is not looking at the right location, or it is started before it is created.

Last, changing the permissions on /etc/hosts to 644 still doesn't make it readable for dnsmasq. The same errors show up at (re)starting dnsmasq.
