Not yet.  The iSCSI initiator requires iscsid(8) in order to work, and you can't
run it before mounting root.

I think the proper way to do this would be by doing something similar to Linux'
initrd; i.e. booting from mdroot loaded by loader(8), run iscsid(8) from there,
setup iSCSI session, then mount the real root and pivot to it.  I'm not sure if it's
possible right now.
