EFI zfs loader and beadm?

[krad]

As Eric said you cant have /boot on a separate dataset as the whole loader
bootstrap isnt designed too look for it on the dataset defined by bootfs.
Remember no other datasets are mounted at that stage of the bootstrap.

You could maybe bodge something by manually playing around with the bootfs
property, symlinks and rootfs variables in the loader.conf.  But why would
you want to do this? It's more work and non standard, and will break a lot?
