Please read this:
http://www.netbsd.org/releases/release-map.html

"This can either be in the form of a major release like 2.0 or 3.0, of
a maintenance (stable) release such as 2.1, or a security/critical
release like 2.0.2."

So if you're happy with 4.0 and ONLY want security fixes, 4.0.1 is for
you.  If you want security fixes and stable  (but possibly new)
features, look out for 4.1.

You can do either.  You should probably do both so you get fixes for
both kernel problems and userland problems.

Specify this with build.sh or let build.sh figure it out if you're not
cross-building.
You can put options in /etc/mk.conf if you really want to.

Userland is everything that is not the kernel (all the programs).
It's important.

Static builds are linker terminology.  If you don't know about it, you
probably don't need it.

Toolchains are the programs needed to build NetBSD.  (gcc, ld, make, etc)
