I did the following, outside the simulator:
tools/assemv2
mkdir fs/usr/kernel
cp -pi build/u?.s fs/usr/kernel
tools/imgbuild
boot/installboot
tools/pdp11 boot/simh.cfg
If you grab the latest svn sources the process is a lot simpler.
You just have to
cd build
make
<cp extra files into root or usr>
rm protofs
make install
but the extra commands aren't necessary because in the latest Makefile
we're installing /usr/src with the commands sources and /usr/sys with
the kernel sources.
msys2 u ../kernel/a.out
Great!
