It might be the documentation that's confused. Here's an extract from
man resolvconf
✄✄✄✄✄✄✄✄
ifup
The ifup program can be used to configure network interfaces
according to settings in /etc/network/interfaces. To make
ifup push nameserver information to resolvconf when it
configures an interface the administrator must add dns- option
lines to the relevant iface stanza in interfaces(5). The
following option names are accepted: dns-nameserver,
dns-search, and dns-sortlist. To add a nameserver IP address,
add an option line consisting of dns-nameserver and the
address. To add multiple nameserver addresses, include
multiple such dns-nameserver lines.
dns-nameserver 192.168.1.254
dns-nameserver 8.8.8.8
To add search domain names, add a line beginning with dns-search.
dns-search foo.org bar.com
The dns-nameservers option is also accepted and, unlike dns-nameserver,
can be given mul‐
tiple arguments, separated by spaces.
The dns-domain option is deprecated in favor of dns-search.
The resulting stanza might look like the following example.
iface eth0 inet static
address 192.168.1.3
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameserver 192.168.1.254
dns-nameserver 8.8.8.8
dns-search foo.org bar.com
✄✄✄✄✄✄✄✄
IOW you should be able to write
dns-nameserver 192.168.1.254
dns-nameserver 8.8.8.8
or
dns-nameservers 192.168.1.254 8.8.8.8
But I have no idea whether
dns-nameservers 8.8.8.8
and
dns-nameservers 192.168.1.254
dns-nameservers 8.8.8.8
are supported. Messy.
Cheers,
David.
