Comment 10 for bug 989585

I don't know of a specific web page to point to,, but a quick Google search for "resolv.conf chattr" turns up quite a number of hits...

However, it seems like people who have done this on their machines have had some specific reason to take an interest in the specific contents of their resolv.conf file, and I wonder if silently undoing that will causes some unhappy surprises....

Another options would be to add pre-upgrade check for this situation in update-manger and give the user a clear warning message before commencing the upgrade.

(Also, would it make sense to expand the Release Notes paragraph on resolvconf to mention this sort of problem? The current brief-mention-with-link-to-blog is pretty easy to miss [and in any case the blog doesn't currently mention the immutable-resolv.conf problem].)
