Yes. Just like in UNPRIVILEGED=yes mode.
For my bulk build program this is not a problem at all
because PREFIX is removed and bootstrap is reinstalled
befiore building every package.
Anyway, everything has its own advantages and disadvantages.

I see. And this level of USE_DESTDIR support is exactly what I'm
talking about.  It whould be great to see pkgsrc with such DESTDIR
support that allows to run bulk builds in FULLY unprivileged mode
including an installation stage. And no, I'm not about UNPRVILEGED=yes.

Stay tuned! Nobody tries to lecture you! I know about all these
assumptions.  You just didn't read my post.

Many packages are already patched for supporting USE_DESTDIR.  Many
packages don't need to be patched at all, either for $DESTDIR or for
using BSD install.  So, what?  Reread my post first.

I know that there are packages that need to be patched for:
DESTDIR support, UNPRIVILEGED support etc. 
This was NOT my question. Did you really read my post?

Yes, I think that FULL DESTDIR support is such level of support that
allows me to run bulk builds without root privileges at all.
"Stupid Linux developers" do so for many years.
Unprivileged build and "prefixed" packaging is big step
forward for pkgsrc but it
is not enough. I repeat fragment of the official documentation that
you skipped.

  5.3. Variables affecting the installation process
  ...

  * Full DESTDIR support can run the complete build, installation and
!                                                    ^^^^^^^^^^^^
    packaging as normal user. Root privileges are only needed to add
    packages.

So, I asked my question because not everything was clear enough for
me. Now I see, the level of DESTDIR support that I need and whould
like to call REALLY FULL "was not the goal".  No problem, but fix the
documentation.

Really? Ah, I forgot: inadequate kids like you always know everything
about everything. "Stupid Linux developers", "I strongly disagree",
"Period!" are always your best arguments.  Beleive me, I know the
difference between UNPRIVILEGGED=yes and USE_DESTDIR=really_full
I asked about.
