  This is NanoBSD build, so it doesn't use system /etc/make.conf and
  /etc/src.conf. I'll try to add it into NanoBSD configs.

  NanoBSD builds world into empty object dir every time. What should I
  `delete-old'?

  Is "system" version (system is snapshot from Mar 30) is "external" and "m=
odern"?

d> 4. Selectively apply to the source tree (all are required for my purpose=
s):
  I'll give it a try.
