How do you get dnsmasq to specify alternate DNS servers?
Solution 1:
Answered my own question, thanks to rfc2132
dhcp-option=6,192.168.0.90,192.168.0.98
However, RFC2132 specifies option 5 as a list of name servers and option 6 as a list of domain name servers, and I'm not sure what the difference is. Either way, option 6 put them correctly as
nameserver 192.168.0.90
nameserver 192.168.0.98
in /etc/resolv.conf

Posting as a separate answer rather than a comment on yours because that way I can use links.
Option 5 is for IEN 116 nameservers — a ridiculously obsolete protocol that Jon Postel wanted dead over twenty years ago. Solaris still supports it, but won't in the next version.
