Thank you for that link. This worked (better).
I'm getting into the 'mountroot>' shell during the boot. Oh well, I'm 
getting better at this.

The ZFS guides on the wiki leave you with a empty root zfs filesystem 
after the installation.
After I know a bit more about ZFS and why the FreeBSD wiki is wrong on 
ZFS installation I hope
to edit them.

Thank you all for your answers,
