Thanks, this got me going in the right direction.  These unit files
seems to be working much better for me, with the startup and shutdown
ordering between iscsi, iscsid, and remote-fs mounts sorted out.  I'm
not sure about the tgtd/targetcli stuff, not sure what the original need
there was.

My non-root test install with /home on iSCSI also has a swap partition
on it, and that's still causing me all sorts of trouble if I don't
comment it out in fstab.  Trying to order all this before swap.target
blew up in my face pretty good.
