[Dnssec-trigger] Version 0.10 on Ubuntu Precise Pangolin: "no DNS servers have been supplied via DHCP"

[Stephane Bortzmeyer]

Did anyone have success with dnssec-trigger 0.10 on the last Ubuntu,
12.04, "Precise Pangolin"?

I always get a "no DNS servers have been supplied via DHCP" even when
there are such servers:

% dnssec-trigger-control status
at 2012-05-21 10:57:54
authority 128.63.2.53: OK 
no cache: no DNS servers have been supplied via DHCP
state: auth secure

Precise Pangolin changed the management of resolv.conf, it is now a
symbolic link towards the version managed by the resolvconf program:

% ls -l /etc/resolv.conf
lrwxrwxrwx 1 root root 29 May 21 10:30 /etc/resolv.conf -> ../run/resolvconf/resolv.conf
