As you might now, I built a new rig recently.  I've built three since I
started using Gentoo.  When I first do a install, I have some default
options for emerge in make.conf.  Once I get all the packages I want to
be in my world file installed, I then go back and add -1 to emerge
options in make.conf.  That way if I run into a problem with a package,
want to install something temporarily or otherwise do something I don't
want in my world file, then it is a one shot emerge by default.  This
keeps my world file clean.  I don't know how many times I've seen people
have problems because a package was entered, often with a specific
version, in the world file and that blocks other updates.  Another bad
thing to have in the world file, library packages. 

With that setting, emerge won't add manually emerged packages to the
world file.  If I install something new that I want to be in the world
file, I override the -1 option by putting --select y on the command
line.  That emerges the package and then adds it to the world file so
that it gets updated when I do my emerge -auDN world.  If I already have
the package installed, I add the -n option so that it doesn't reemerge
and compile it again.  It just checks to make sure things are installed
correctly and adds the package to the world file. 

I've been doing it this way for a long time.  Likely since I found out
about the -1 option which was a long time ago, likely my first build.  I
don't have to remember to add the -1 option on the command line when
trying to work around a problem or just wanting something for a one time
use.  Once I finish a install, I rarely add anything new so even having
to add the --select y is not used very often. 

On a system while installing, the -1 option isn't a good idea.  Once
that is done tho, I think it is best to have it set as the default.  It
is the easiest way to make sure that the only things that go in the
world file is only what you want in there.  Packages that you use
directly.  I'm not sure why this isn't mentioned in the install handbook
as a best method once a install is done.  Unless it has been added and I
don't know it yet.  ;-) 

You mentioned using sets.  I tried using sets.  All it did was create
more work.  If I have something installed here, I use it, sometimes a
LOT.  Therefore, I want them all to be as up to date as is available.  I
found that even when I did have sets, the sets were in the world file
and being updated anyway.  No real point in that when just putting for
example, kicad-meta, in the world file and skipping the sets.  Some may
like it.  I've read of people using and liking how it works.  For me
tho, it was just more work.  So, some of us long term users do just fine
without sets.  :-D 

Over the years, I've came up with a method of updating my system and
default options for emerge that works well.  My packages are stable and
crashes are rare.  I can't even recall the last crash.  I'd be more than
happy to share some of those settings and my steps if interested. 

Just something for you to think on.
