I agree, we could automatic five sudo access to admins.
Or, as an alternative, we can create an ad-hoc group.
@bwdjames you can solve your problem like this (not tested):
- create a group
powerusersin Users & Groups page - add one ore more user to the group
- create a sudo file like this:
echo "%powerusers ALL=(ALL) ALL" > /etc/sudoers.d/90powerusers
chmod 440 /etc/sudoers.d/90powerusers
