The reason the role declarations are in kernel.te is because of the user
declarations in policy/users. If you turn off unconfined, then base
fails to compile.
One option may be to eliminate all user declarations except system_u,
and then it would be up to the distros/users to create their own users
(even if it is just to restore what we currently have). That being
said, I don't like that option much, as refpolicy can't work out of the box.
