Also ima_appraise_tcb is not necessarily more restrictive. It takes
appraises only for root user. Files for rest of users are not appraised.
In general case of "memory locked execution of signed binary" I was
hoping to give user a flexibility to do appraisal either for root
or both root and non-root user.
For the time being I can hardcode things only for root user but the
moment somebody will extend functionality for non-root user, again
we will run into the issue that ima_appraise_tcb is not superset so
we can't allow that.
Thanks
Vivek
