Can I install dnsmasq as well as (instead of?) dnsmasq-base?

dnsmasq provides local dns on the LAN and passes anything for which it
doesn't know the answer on to the 'real' DNS servers 'out there'. 
That's its major function in life.  When it also provides DHCP services
the systems on the LAN provide it with their names so that one can use
names for all of one's local systems.

Oops, that was supposed to be pasted in there!  :-)

It's in /etc/NetworkManager/NetworkManager.conf, if you take it out then
Network Manager doesn't run dnsmasq for you.
