In Debian-Squeeze all works out of the box. Also separate root-account, group "admin" does not exist at all, user running update-notifier does not need to be (and is not by default) member of groups "adm" nor "sudo".
Conclusion:
Lucid's alternate-CD has been made a very frowsy way as this is not the only complaint on it.
