Comment 3 for bug 1821255

I've updated the description with a simpler test case that doesn't require an
override file, but this bug can also be verified with the Restart=always directive:

ubuntu@disco:~$ cat /etc/systemd/system/iscsid.service.d/override.conf
[Service]
Restart=always

ubuntu@disco:~$ sudo pkill iscsid

ubuntu@disco:~$ sudo systemctl status iscsid
● iscsid.service - iSCSI initiator daemon (iscsid)
   Loaded: loaded (/lib/systemd/system/iscsid.service; disabled; vendor pre
  Drop-In: /etc/systemd/system/iscsid.service.d
           └─override.conf
   Active: inactive (dead)
