# Setup our resolv.conf
# Vitally important that we use the domain entry in resolv.conf so we
# 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
