># Description:
>#	Works around inappropriate parameters used by libvirt to call dnsmasq.
>#	The default parameters used by libvirt prevent dnsmasq from answering
>#	DNS queries for the virtual machines that are assigned IP addresses
>#	via DHCP.
># Installation instructions:
># 	Renamed /usr/sbin/dnsmasq to /usr/sbin/dnsmasq.real.
># 	Install this script as /usr/sbin/dnsmasq
># 	chmod 755 /usr/sbin/dnsmasq
>#
