rsyslog-gnutls is not installed when enable-os-refresh-update is false

[Menno Finlay-Smits]

The rsyslog-gnutls package is essential on state servers for the rsyslog configuration used by Juju, however Juju only instructs cloud-init to only install the package if enable-os-refresh-update is true. Without rsyslog-gnutls installed, connections to rsyslogd on the state servers fail, with continuous errors being reported in /var/log/syslog by rsyslogd and large amounts of log spam in agent logs as the rsyslog worker tries to connect.

Given that rsyslog-gnutls is available without special handling in all supported series there is no reason to selectively install it. Similarly, other packages such as curl are unnecessarily limitied in the same way.

This seems like a serious issue to me. (Possibly a critical regression, though I'm not sure the support we had for enable-os-refresh-update in the past.)
Certainly if enabling this means logging breaks, that's a serious break.

This is the result of https://github.com/juju/juju/pull/621, which was partially fixed, for precise, as a side-effect of the fix for bug 1424777.

Marking as critical because Juju fundamentally breaks because rsyslog does not work.

I saw this while refactoring the cloud init stuff. Was thinking of making a list of packages that are needed and a list of packages that should only be updated(if there even is such a need).

Is there any particular reason why we're only updating those packages and not installing them every time?

[Ian Booth (wallyworld)]

The fact that packages required for Juju are not installed when needed is a bug and there's no special reason not to install them if needed.
