          local
....

This work fine, booted, beadm create new env, activate them, see boot
menu and select BE.

% beadm list
BE    Active Mountpoint  Space Created
init  -      -          420.7M 2016-03-09 02:57
init0 NR     /           35.9G 2016-03-10 05:00

If i'm add separate dataset for /boot (efiwpool/ROOT/init0/boot)
system not booted, efi loader (first stage) see only my pool, not
found /boot/loader.efi
