LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

4 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

$ lxc exec enormous-quetzal apt policy open-iscsi
open-iscsi:
  Installed: 2.0.873+git0.3b4b4500-14ubuntu17

So things are better generally. I'm not sure if this is high enough
priority where we might want to consider SRUing some of the changes back
to 16.04?

Also, Serge, I was looking at your change from c#17 -- does that mean
even privileged containers would no longer get their iSCSI devices to
start? (iscsiadm mentions that iscsid is often needed) And shouldn't we
do the same (to be consistent) for iscsid.service? Actually, it seems
like if we had done it in iscsid.service, the following:

ExecStartPre=/bin/systemctl --quiet is-active iscsid.service

from open-iscsi.service would have avoided needing to change open-
iscsi.service at all?
