It appears that enough binpkgs merged to provide a working portage environment

I was late with adding genkernel to emerge gentoo-sources suggest

Be aware that genkernel builds its own versions of everything that goes in the initrd.
It does not take binaries from the system - it may not even use the same versions as the system

OK, thanks. I will try to do that as soon as I can. I have to sidestep for some other tasks for a shortwhile though.

We configured menuconfig,
make all
it worked fine
but next step
make install

make install

System.map "/boot"

I have got our local Linux guru help me out here, but he used everything but Gentoo! Now BzImage was copied after unmount /boot
and mount /boot, which made the /boot rw.
