Ubuntu 14.04 contains buggy init script for open-iscsi

[Dmitriy Stremkovskiy]

Distributor ID: Ubuntu
Description: Ubuntu 14.04.5 LTS
Release: 14.04
Codename: trusty

open-iscsi 2.0.873-3ubuntu9

/etc/init.d/open-iscsi contains
# Default-Start: S

but should contain
# Default-Start: 2 3 5

Current script prevents open-iscsi to start at boot time on 2,3,5th runlevels
Expected: open-iscsi should be able to start on 2,3,5th runlevels

Workaround(fix) as root:
sed -i -re 's/^#[\ \t]*Default-Start:[\ \t]*S[\ \t]*$/# Default-Start: 2 3 5/' /etc/init.d/open-iscsi
update-rc.d -f open-iscsi remove
update-rc.d open-iscsi start 20 2 3 5 . stop 20 0 1 6 .
update-rc.d open-iscsi enable
