> CsDhcp.process() appends new entries to /etc/dhcphosts.txt causing duplicates like:
> {code}
> 06:49:14:00:00:4d,10.7.32.107,node1,infinite
> 06:42:b0:00:00:3a,10.7.32.107,node2,infinite
> {code}
> This makes dnsmasq fail with "no address available".
> CsDhcp.process() should repopulate the file to remove old entries with the same IP address.
