Well, sorry for not being explicit enough -- after all, we're both non-native

Now, examining my setups, I'm not quite sure what could we do in 
non-deterministic situation like I've created myself :)

Understood, and this is fair enough.  

Now, looking at zfsboot.c, couldn't we (for finding /boot/zfsloader suitable
