Subject: network: don't use dhcp-authoritative on static networks
|
|
|
|
"Static" DHCP networks are those where no dynamic DHCP range is
|
|
defined, only a list of host entries is used to serve permanent
|
|
IP addresses. On such networks, we don't want dnsmasq to reply
|
|
to other requests than those statically defined. But
|
|
"dhcp-authoritative" will cause dnsmasq to do just that.
|
|
Therefore we can't use "dhcp-authoritative" for static networks.
|
|
|
|
Fixes: 4ac20b3ae "network: add dnsmasq option 'dhcp-authoritative'"
