according to boot(8) man page, 'it is possible to dispense with the third stage altogether'. however, 'hitting a key' and specyfing '0:ad(0,a)/boot/kernel/kernel' results in hard hang (impossible to reboot with crtl-alt-del) at spinner (/-\|). booting '0:ad(0,a)/boot/ loader' works ok.
State Changed From-To: open->closed In this particular release this is supported, but you need the hints for syscons and probably atkbd* to make it work. It's possible to compile the hints statically into a kernel.
