> resolvconf/linkify-resolvconf: false
This is always the case after installation because the Ubuntu resolvconf
postinst does the following.
db_set resolvconf/linkify-resolvconf false
This is done for a good reason: it is done in order to prevent the
postinst from attempting to linkify again on upgrade. Thus the admin can
remove the symlink /etc/resolv.conf if she wants to and even though she
doesn't bother to change the answer to resolvconf/linkify-resolvconf,
the symlink won't be recreated on package upgrade.
As I wrote in #1085849, however, I'd like to see another mechanism used
to achieve the same end, so that we can tell what the original answer to
resolvconf/linkify-resolvconf was in cases like this where the symlink
is mysteriously missing after installation. In Debian I have just
implemented this feature another way. The Debian postinst doesn't change
resolvconf/linkify-resolvconf; instead it creates a flag file and
refrains from linkifying again if the flag file is present. I hope that
Ubuntu adopts this mechanism too when 1.71 is merged.
Anyway, Vince, despite the foregoing, can you shed any light on why the
symlink /etc/resolv.conf might have been missing from your system after
upgrade? Which distro and flavor did you install originally? Is it
virtual hardware? Any unusual images used? Any unusual preseeding done?
Any unusual VPN client or similar installed?
(You probably already know that you can recreate the symlink by running
"sudo dpkg-reconfigure resolvconf".)
