Re: EFI zfs loader and beadm?

Its also worth pointing that if you decouple the userland from the kernel
files you no longer have a boot environment, as all the basic stuff to boot
the os isn't contained within the bootfs. I'm still struggling to see why
/boot needs to be on a different dataset, its just a bit of a linuxism.
