I just checked a vm desktop install of jaunty.  That is identical to my
karmic laptop.

$ sudo grep admin /etc/sudoers
[sudo] password for ubuntu:
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

By default on ubuntu, members of the admin group can sudo with their
password.  On ec2 images, the ubuntu user can sudo *without* a password.

I believe the request here was to add the group 'admin' back to sudoers so
that methods to add root access to a user would work on ec2 the same as on
non-ec2.

At least, what I was intending on doing was insert an admin line before
'ubuntu's entry, so that members of the group admin could use sudo to
become root by providing their password.  Ie, new /etc/sudoers would
have:

root    ALL=(ALL) ALL
ubuntu  ALL=(ALL) NOPASSWD:ALL
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL
