They should, but there are exceptions. For instance stuff done via port
select is not covered in the database. I'm sure there are other
examples, too, but I don't know any off-hand. I wouldn't know a use case
for not registering files off-hand either.

Yes, probably, but I cannot remember those details.

Trace mode ALLOWS:
- access to (most?) things outside of ${prefix} that is not /usr/local
- access to files registered by a direct or indirect dependency of
the port to be built within ${prefix}
- access to files NOT registered by ANY port
Trace mode FORBIDS:
- access to files in /usr/local
- access to files in ${prefix} which are not owned by direct or
indirect dependencies
Is this better?
