Code review comment for lp:~mterry/update-notifier/pkexec

While you're right that the Depends is technically in the wrong place, in practice lots of the relevant images have update-notifier installed as well as update-notifier-common, thereby causing cddistupgrader to work. Do you think you could allay any regression concerns by implementing my suggestion for cddistupgrader?

The backend_helper change indeed looks better now.
