A completely empty make.conf is "sensible," so when in doubt, leave it out.

Okay; if you only have one machine, and are ready to bootstrap your
executables from a fresh install if you need to move to another,
that's fine.

This one's worthwhile; most people should use this setting.
Probably the only setting worth worrying about for a typical user.

You're not using this anyway, so don't bother re-setting it.

Why?  

Unless you have a good reason, that's a bad idea.

Probably not a great idea.  Even if you're not running named, you're
probably using resolver code from there.

You're saving yourself a small amount of build time, but that's all.
Note that NOGAMES excludes some useful programs (not that primes(6), for
example, has changed in a long time) and NOSHARE is inadvisable unless
you really modify that stuff heavily by hand.

I'd leave these at the defaults, because you (probably) already have
the programs installed, so you may be better off with the latest
versions.

This is the default anyway, no?
