Of course I understand it.

### bootstrap-depends is a public target to install any missing

This is for in-place package building. Right?  In case of distbb,
tools like wget,rsync,sudo,screen etc. are installed to /usr/pkg_distbb and
are not touched at all while bulk building.

I don't understand this. If tnftp and wget can be added BOOTSTRAP_DEPENDS,
why pkg_tarup cannot. 'make replace' is run after 'make depends'.

It is not _required_ but _may_ be used instead of 'make install'
for bootstrap packages always installed and marked as "not for deletion".

I think crossbuilding is completely different and much harder question.
Currently distbb doesn't support crossbuilding.

Is pkgsrc ready for it?

Is there roadmap/plan/future_API?
Should crossbuilding support be implemented in pkgsrc itself
or in the separate and completely independant projects like
bbf/pbulk/distbb etc. is another question.
