It depends, you can boot using an initrd with SW iSCSI support (either
off a local card or via netboot) and have the rootfs on an iSCSI LUN
and there's a few people have done that with the Trimslice as a PCIe
attached gig interface tends to be faster than usb2 attached SSD.

If you mean via an iSCSI HW device with appropriate firmware and
firmware provided iSCSI LUN where the OS just sees the usual /dev/sdX
style devices we don't currently see that functionality but I wouldn't
be surprised if it was available of some Server SoCs soon.
