If I remember correctly, whenever I try to use ZFS in the installer :

1) the Guided (Root On ZFS) approach simply does not let me select a=20
slice. I have to use the entire disk

2) Using manual partitioning on my MBR disk (SSD), if I delete an=20
existing slice, create a new one, and then a partition inside it of type=20
freebsd-zfs with / as mount-point, the installer warns "This=20
configuration is not bootable in your architecture".

I got around this by using a 2-partition 'hack' in the slice :

a) first partition for / as type freebsd-ufs
b) second partition for /usr as type freebsd-zfs

The install goes through with no warning, but then when I boot the=20
installation, I face the problem that /usr is not available and the boot=20
is interrupted midway with an unpleasant message.
