That's a given and not a problem. What I fear from my understanding of this thread so far is that there might be a situation when I upgrade the zpool and the boot loader and the system ends up unbootable nonetheless. Possible or not? Modulo bugs, try test systems first, etc. Of course. Thanks, Patrickhelp
