Using Geom to mirror root partitions?

I've been a bit out of touch with developments recently.  I was
wondering whether it's possible to mirror root partitions across two
drives yet?  I seem to remember that this was something that geom could
help with, but I've no idea as to whether it's a reality yet.

Does anyone know?
