As far as I know it can't be done from installer. You create a mirror using two entire disks and then slice it up. This requires installing, setting up the raid, slicing the raid, rebooting, making it bootable and migrating the installed stuff to it, and finally rebooting and telling it to boot from one of the raided disks. I've not had time to fully test this, but I am currently playing around with it. I don't like the idea of mirroring partitions because replacing a disk means having to repartition/slice the disk.
