Comment 3 for bug 671016

As a first step we should make sure that users on a unsupported release do not upgrade to a unsupported release without knowing about it). This can happen now on intrepid to jaunty.

As a first (and important step) we should create a file like
the following:
http://bazaar.launchpad.net/~ubuntu-core-dev/update-manager/main/annotate/head%3A/DistUpgrade/EOLReleaseAnnouncement

for the old releases that explains that the release is no longer supported, what that means
and what options the user has. I'm happy to adjust the text/wording as needed, this is just a suggestions.

Then we add this new file as a link for "ReleaseNotes" for all EOL releases here:
http://changelogs.ubuntu.com/meta-release

This way a user trying to upgrading from e.g. intrepid to jaunty (unsupported to unsupported)
will see this text that explains whats going on before the upgrade is performed. We could
have a additional "AlmostEOLReleaseAnnoucement" when the time is close if we want.

This solves the problem that the user has no information on upgrade if the next version is
EOL as well.
