[Bug 1062544] [NEW] Modified permissions after migration /run/resolfconf/resolv.conf

[bggo]

Public bug reported:

Hello,

We had a major issue upgrading some servers to Ubuntu 12.04, we have
hundres of servers runing 11.04.

We belive the problem can be in the upgrade process, it change file
permissions of /run/resolvconf/resolv.conf

In Ubuntu 11.04 or Ubuntu 11.10 the permission is:
-rw-r--r-- 1 /run/resolvconf/resolv.conf  root root 66 Oct  5 12:06  (644)

But after the migration to 12.04 the permissions was :

-rw------- 1 root root 66 /run/resolvconf/resolv.conf  Oct  5 12:06
(600)

We realised this just because apache stoped to resolve names. We write a
simple php script using gethostbyname function to test. As root
everything just fine, as normal user didn't work. So we check dig and
host as root and as normal users and confirm that the permission were
the problem.

What does it afecct: Name resolution of a normal user. Apache and many
other services are started by "services users" that can't resolv names
to.

We deploy also a new Ubuntu 12.04 and Ubuntu 12.04.1 to check if was a
problem on the package and the permission was just fine, so everithing
points to the upgrade proccess.

By any chance this is a bug?

Kind Regards
