My interpretation of what "build" referred to for
etcupate was way off. I've added the -B's that I
was not using before.

Thanks for the note!

Yep: that added what leads to the dtc build.

I still wonder if etcupdate builds more than it needs to
for its specific pruposes when it does do a build:
building dtc in order to complete an etcupdate just seems
time/resource wasting.

But, at least I'm using -B in the future.

An example was: `-- /bin/sh /usr/sbin/etcupdate -D/usr/obj/DESTDIRs/main-CA7-chroot -s /usr/main-src -M TARGET_ARCH=armv7 `-- make TARGET_ARCH=armv7 -DNO_FILEMON buildetc `-- make -m /usr/main-src/share/mk -f Makefile.inc1 TARGET=arm TARGET_ARCH=armv7 buildetc `-- make -f Makefile.inc1 _bootstrap-tools MK_CROSS_COMPILER=no MK_TOOLCHAIN=no . . . `-- /bin/sh -e -c echo "===> usr.bin/dtc (obj,all,install)"; cd /usr/main-src/usr.bin/dtc;. . . install `-- make DIRPRFX=usr.bin/dtc/ all `-- c++ -O2 -pipe -fno-common -DNDEBUG . . . -c /usr/main-src/usr.bin/dtc/fdt.cc -o fdt.o More may build. This is just what was present when I happened to look. Seems an odd thing to be happening for an etcupdate . I'll note that aarch64 targeting aarch64 (self hosted build) also spends notable time and is likely doing similarly. === Mark Millard marklmi at yahoo.com
