So if there was an "easier" way, I'd sure like to see an example.
If you fully install 2.7_alpha3, you get a "dns-updown" script
in the "libexecdir" (like, /usr/local/libexec/openvpn/dns-updown).
If there is *no* --up script set, OpenVPN will call said script
(in the compiled-in location) automatically and it should do all the
magic.
If --up is in use, we decided to not mess with people's pre-existing
configurations - in that case, the DNS script is not run and "everything
stays as it is".
If you have an --up script doing something else, and still want the new
DNS script, use "--dns-updown force" ("always run the compiled-in script"),
or if you want something else, use "--dns-updown /path/to/my/script.sh"
(this will need --script-security 2).
The --dns-updown section in the manpage explains more about the script
and the conditions when and how it's called, and how --dhcp-option DNS
and --dns interact ("do not break people's setup" leads to quite some
contortions at times - I hope we got it mostly right for DNS)
