Looks like it is being triggered by the dontaudit domain self:capability sys_module; rule in the marlin sepolicy/domain.te file. dontaudit rule merging differs since they are converted to auditdeny vectors. Likely a bug in checkpolicy but will have to look at the logic.

They both have the same "dontaudit su self:capability_class_set *"
statements, yet one compiles differently than the other.
nnk@nick:~$ wget -q http://kralevich.com/bullhead.policy.conf
nnk@nick:~$ wget -q http://kralevich.com/marlin.policy.conf
nnk@nick:~$ grep "dontaudit su" bullhead.policy.conf
marlin.policy.conf | grep capability
bullhead.policy.conf: dontaudit su self:{ capability capability2 } *;
marlin.policy.conf: dontaudit su self:{ capability capability2 } *;
And changing from
dontaudit su self:{ capability capability2 } *;
to
dontaudit su self:capability *;
dontaudit su self:capability2 *;
has no effect and the policy continues to not pick up the neverallow rules.
