Sort of...

The type of granularity I was referring to was cumulative.

For example, what I can't do is:

Setup a rule which says:
sudoUser: jaquino
Permit ALL
SudoOrder: 0

And a granular rule which says:
sudoUser: jaquino
Deny reboot/halt/shutdown
sudoOrder: 1

The desired result being: If I run any command except for

Except, it would seem in this scenario:

Sudo will Always hit the deny rule with the priority 1, see that there are
no additional Permit lines.

Thus, no matter what command I run, I will always be denied and the permit
rule will never be read.
