Comment 16 for bug 209429

FYI, I've now done an upgrade of a system from edgy->feisty->gutsy->hardy, and at no point did /etc/timezone disappear. Given that /etc/timezone has been present out-of-the-box since at least edgy, and all of the relevant maintainer scripts handle it correctly, this bug basically requires some package or script to have gone out of its way to remove the file; so I'm at a loss on how to proceed here.
