 From the man page for the current version of dnsmasq: If yours doesn't 
say this, you may have to upgrade: I can't find the exact version at 
which the directory-reading facility was added, but it was fairly long ago.

-H, --addn-hosts=<file>
    Additional hosts file.  Read  the  specified  file  as  well  as
    /etc/hosts.  If  -h is given, read only the specified file. This
    option may be repeated for more than one additional hosts  file.
    If  a  directory  is given, then read all the files contained in
    that directory.

Cheers,
