+# can setup the nameservers are for the domain ONLY in resolvconf if
+# we're using a decent dns cache/forwarder like dnsmasq and NOT nscd/libc.
+# nscd/libc users will get the VPN nameservers before their other ones
+# and will use the first one that responds - maybe the LAN ones?
+# non resolvconf users just the the VPN resolv.conf
+
+# FIXME:- if we have >1 domain, then we have to use search :/
+# We need to add a flag to resolvconf to say
+# "these nameservers should only be used for the listed search domains
+# if other global nameservers are present on other interfaces"
+# This however, will break compatibility with Debians resolvconf
+# A possible workaround would be to just list multiple domain lines
+# and try and let resolvconf handle it
