The correct answer for this is "it depends".  Each set can be
configured to be included or not in the world_sets file, based usually
on the type of set.

The file /usr/share/portage/config/sets/portage.conf declares many
sets, setting "world-candidate = True" for some of them.  Others (like
@world, @selected, and @system) are not candidates for @world.  Note
that the "@world" set itself is declared to be exactly the three sets
"@profile @selected @system" -- @system is the usual system set,
@selected is the contents of the "world" and "world_sets" files, and
@profile is certain packages that used to be defined as required in
profiles without being listed in @system (I don't believe this
functionality is used in the tree any more).

Don't worry, a lot of us learned that the hard way.

Thanks much for the lesson.  I may hijack more of the OP's threads to
ask about trivia.  :)

$ sudo emerge --noreplace @testset
Calculating dependencies... done!

I had also been under the mistaken impression that --update 
implied --oneshot, but I see that it's not so.

@module-rebuild is a dynamic set. It translates to "all the packages you
have emerged that install out-of-tree kernel modules"

So not really a fair comparison. Compare instead against a regular
static set - "a bunch of packages defined by you that go together and
live in /etc/portage/sets/"

Hmm, that doesn't match my experience.  I just tested with the smallest
set I ever use, @module-rebuild :

# emerge @module-rebuild
Calculating dependencies... done!
>>> Verifying ebuild manifests

 * GNU info directory index is up-to-date.
# cat /var/lib/portage/world_sets 
# file /var/lib/portage/world_sets 
/var/lib/portage/world_sets: empty

I don't think I have anything in make.conf which would change the
default behavior WRT world_sets, but here's what I have anyway:

FEATURES="binpkg-logs buildsyspkg collision-protect downgrade-backup
 fail-clean fixlafiles news parallel-fetch parallel-install
 preserve-libs sandbox strict unknown-features-warn userfetch
 userpriv usersandbox usersync"

EMERGE_DEFAULT_OPTS="--ask-enter-invalid --jobs=8 --load-average 11.2 
--with-bdeps y"

Effectively, yes. That's not what the code does of course (they go into
world_sets) but the behaviour is as if the set was in world, and gets
added/removed as a complete unit

When the target is a set (in this case @system), does portage ever add
all of it to @world?

Apparently it does not. I know it does that for individual packages, so
I just assumed it did that for sets as well. I stand corrected.
