Your dataset hierarchy is not what beadm expects. Specifically, you
have /boot separate from /, which I imagine is causing your problem.
/boot should be part of /. Also, you have several file systems in the
BE that are usually not in it; I doubt this is part of your boot
failure, though.
For reference, here is my layout, which is mostly the same as the
default installation:
