Hello,

Is there a way to have an OpenVPN server push dhcp-options to the
clients that completely replace any existing entries in
/etc/resolv.conf?  

Using these OpenVPN settings on the server:

  push "dhcp-option DNS 10.8.0.1"
  push "dhcp-option DNS fd00:10:8::1"
  push "dhcp-option DOMAIN debian.org"

VPN'ed clients see this in /etc/resolv.conf

  # Dynamic resolv.conf(5) file for glibc resolver(3) generated by
    resolvconf(8)
  #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE
    OVERWRITTEN
  nameserver 10.8.0.1
  nameserver fd00:10:8::1
  nameserver 8.8.8.8
  search debian.org some-isp.tld

Note the ISP supplied "8.8.8.8" and "some-isp.tld" entries that remain
in /etc/resolv.conf after connecting to the VPN.

tia,

-Jim P.
