------------------------------
Summary: Adding ext_sshd service fails Ubuntu 16 images
Key: VCL-989
URL: https://issues.apache.org/jira/browse/VCL-989
Project: VCL
Issue Type: Bug
Components: vcld (backend)
Affects Versions: 2.4.2
Reporter: Andy Kurth
Assignee: Andy Kurth
Fix For: 2.5
Ubuntu 15.04 and later no longer uses the Upstart init daemon as the default.
The ssh/sshd service on Ubuntu 15.04+ is now controlled by systemd. As a
result, VCL's systemd.pm module controls the service instead of Upstart.pm.
Ubuntu uses *ssh* as the service name instead of *sshd*. There is code in the
Upstart.pm module to counteract this insanity. Unfortunately, the systemd.pm
module does not have such code and fails to add the ext_sshd service:

The *systemd.pm* module now controlling the sshd/ssh service on Ubuntu assumes
the unit file is located at:
/lib/systemd/system/*sshd*.service
It's actually located at:
/lib/systemd/system/*ssh*.service
Code should be added to systemd.pm to determine the correct path of the unit
file for the sshd service rather than assuming it is in the standard place.
