That has changed in newer policies.  But regardless, if you want to be
able to see allows/denies on ai_t, you can't make it an alias - it needs
to be its own distinct type.  Aliases are just turned into the same
underlying type internally, so they will still show up as unconfined_t
in audit messages and ps -Z output.
