Yes, target would be what's passed by the user, like:

"iqn=iqn.1994-04.org.netbsd.iscsi-target:target0,portal=192.168.1.128"

And pdev_path would be filled after the device has been attached, and it
will be something like:

/dev/sdb

The main reason we need the block device is to be able to call pygrub or
to pass it to Qemu.
