[Bug 1465196] Re: open-iscsi init script creates dependency cycle with NetworkManager

[Vincent Ladeuil]

For the record, on a wily system, there is still a dependency loop
involving open-iscsi but system can still boot successfully.

Roughly, I can do:

# apt-get install open-iscsi
# iscsi_discovery <iscsi server IP>

and see the expected volumes

But rebooting from there causes the dependency loop and open-iscsi is
not started on next reboot.

I'll try to reproduce in a vm to provide better info.
