** Description changed:
- I have a VPN set up in Network Manager, which worked well when my system
- was running 11.10.
+ [rational]
+ When using ppp from Network Manager (VPN or modem), the hook script from
resolvconf will be triggered and adds the DNS directly to /etc/resolv.conf.
+ That's wrong as Network Manager already handle these and can lead to broken
DNS resolution.
+
+ [test case]
+ 1) Setup a connection in Network Manager using a ppp backend
+ 2) Connect
+ 3) Check that only 127.0.0.1 is present in /etc/resolv.conf
+ 4) Check that /run/resolvconf/interface/ppp0 doesn't exist
+
+ [regression potential]
+ The change in the check only applies to the case where the script is called
with "nm-pptp-service-", so only potential regression I can see is a case where
someone manually runs ppp with the exact same parameter as Network Manager, but
that'd be wrong...
+

+ I have a VPN set up in Network Manager, which worked well when my system was
running 11.10.
After upgrading to 12.04, I've noticed that DNS changes needed by the
VPN aren't happening. Hosts that only resolve within the VPN won't
resolve, and hosts that are supposed to resolve with different IP
addresses inside the VPN don't.
I can see the new, proper nameserver configuration in /var/run/nm-dns-
dnsmasq.conf. I can resolve properly if I query the name server
directly, i.e. "host <name-to-resolve> <vpn-dns-server-ip>". And, if I
use that IP address instead of the name, I can successfully do things
like ssh. But simple resolution appears to still be using the old name
server.
At one point, I killed off dnsmasq and wrote a new /etc/resolv.conf with
the VPN name servers. That worked, but caused all manner of problems
later.

Title:
/etc/ppp/ip-up.d/000resolvconf should "exit 0" if pppd was run by NM,
since NM will register the nameserver addresses itself
