Description of problem:

many users want to use sudo because it support command completion and because it preserve the rights for some time and it doesn't open the root account fully.

How reproducible:
$sudo defaultuser

a message will appear stating that you aren't in the sudoers file.

Steps to Reproduce:
1.$sudo defaultuser

Actual results:
a message will appear stating that you aren't in the sudoers file.

Expected results:
to do the command as super user

in #fedora-devel
<blarney> it probably could be added as an option to "firstboot"

I think it should be enabled by default for the default user
