Normally an update build is fairly fast but still does a lot of running
make that results in no commands being run.  Some tool bootstrapping
(nbmake only?) is always done.

See pkgsrc/sysutils/etcmanage for BUILD-NetBSD, a commented example of
how I use

If you still think -u is misbehaving, please post your commands.

It's likely the basic issue is the difference between privileged and
unpriveged builds, which is new with NetBSD.   Builds are typically done
as non-root, and 'make install' doesn't set owner/suid/etc. but instead
records this in METALOG.  Then one can also install with DESTDIR=/ as
root.  My script has examples.

I use absolute paths for TOOLSDIR and OBJDIR.  I'm not sure that

FWIW I do a full build all the way to iso and then do binary updates
From the resulting sets.  See INSTALL-NetBSD (in etcmanage) for how I do
it.  That lets me do the build on one machine and install on another -
and the source machine doesn't have to be the same architecture.   I
have been updating aging ultrasparc 5s like that for years.

Yes, it is the appropriate lits.
