You can do that if you want. "build.sh" makes that very easy. But it is
not necesasry.

You don't even need to rebuild the kernel. A lot of people (including me)
however prefer that to get a smaller kernel with less unnecessary drivers,
filesystems etc..

If you update NetBSD via sources you will have to do that, too. You can
however use "build.sh" to accomplish both task.

Yes, please use "CPU_FLAGS" for that purpose. Here is an example:

CPU_FLAGS=      -march=pentium3

Please do *not* set "CFLAGS". You might break the NetBSD build and you
will for sure break the build of some of the packages in "pkgsrc".

Yes, it. Userland is the term used for everything except the kernel
(binaries, libraries, manual pages, include files, etc.). So you
will definitely need it.

Don't worry about static builds, you don't need them. The toolchain
is the set of tools which is required to build NetBSD. This includes
of course the compiler and linker but also tools to generate manual
pages and other data files. "build.sh" will those for you automatically.

        Kind regards
