It will work fine, but the system resolver might end up querying an nameserver other than dnsmasq(localhost) which is exactly, if I understood correctly, what /dev/rob0 wants to avoid. That said, dnsmasq will poll your alternate resolv.conf for change automatically, unless requested otherwise (--no-poll), so I see no need to restart it after a change. This is actually what I was doing* on my laptop, a custom dhcp client hook will fill an alternate resolv.conf file : /etc/resolv.conf-dnsmasq (used by dnsmasq), and ensure /etc/resolv.conf only contains the localhost nameserver with optionnal supplementary parameters (search,...) This is obviously usefull for dnsmasq cache and other features (eg: server=//), but also for some services/daemons which don't poll /etc/resolv.conf for change on their own(eg: postfix) _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
