It is possible to have previously installed certbot, but switched back
to using self-signed certificates -- in which case renewing them using
certbot may fail.
Verify that the certificate is a symlink into certbot's output
directory before running `fix-standalone-certbot`.
Commit f6d27562fa (#21564) tried to
ensure Chrony is running, which fails in containers where Chrony
doesn’t have permission to update the host clock.
The Debian package should still attempt to start it, and Puppet should
still restart it when chrony.conf is modified.

Since wal-g does not provide binaries for aarch64, build them from
source. While building them from source for arm64 would better ensure
that build process is tested, the build process takes 7min and 700M of
temp files, which is an unacceptable cost; we thus only build on
aarch64.
Since the wal-g build process uses submodules, which are not in the
Github export, we clone the full wal-g repository. Because the
repository is relatively small, we clone it anew on each new version,
rather than attempt to manage the remotes.
Fixes#21070.
The default timeout for `exec` commands in Puppet is 5 minutes[1]. On
slow connections, this may not be sufficient to download larger
downloads, such as the ~135MB golang tarball.
Increase the timeout to 10 minutes; this is a minimum download speed
of is ~225kB/s.
Fixes#21449.

This commit adds a cron job which runs every hour to add the users to
full members system group if user is promoted to a full member.
This should ensure that full member status is available no more than
an hour after configuration suggests it should be.
Previously, it was possible to configure `wal-g` backups without
replication enabled; this resulted in only daily backups, not
streaming backups. It was also possible to enable replication without
configuring the `wal-g` backups bucket; this simply failed to work.
Make `wal-g` backups always streaming, and warn loudly if replication
is enabled but `wal-g` is not configured.
It would confuse a future Debian 15.10 release with Ubuntu 15.10, it
relies on the legacy fact $::operatingsystemrelease, the modern fact
$::os provides this information without extra logic, and it’s unused
as of commit 03bffd3938.

Zulip writes a `rabbitmq.config` configuration file which locks down
RabbitMQ to listen only on localhost:5672, as well as the RabbitMQ
distribution port, on localhost:25672.
The "distribution port" is part of Erlang's clustering configuration;
while it is documented that the protocol is fundamentally
insecure ([1], [2]) and can result in remote arbitrary execution of
code, by default the RabbitMQ configuration on Debian and Ubuntu
leaves it publicly accessible, with weak credentials.
The configuration file that Zulip writes, while effective, is only
written _after_ the package has been installed and the service
started, which leaves the port exposed until RabbitMQ or system
restart.
Ensure that rabbitmq's `/etc/rabbitmq/rabbitmq.config` is written
before rabbitmq is installed or starts, and that changes to that file
trigger a restart of the service, such that the ports are only ever
bound to localhost. This does not mitigate existing installs, since
it does not force a rabbitmq restart.

This is required in order to lock down the RabbitMQ port to only
listen on localhost. If the nodename is `rabbit@hostname`, in most
circumstances the hostname will resolve to an external IP, which the
rabbitmq port will not be bound to.
Installs which used `rabbit@hostname`, due to RabbitMQ having been
installed before Zulip, would not have functioned if the host or
RabbitMQ service was restarted, as the localhost restrictions in the
RabbitMQ configuration would have made rabbitmqctl (and Zulip cron
jobs that call it) unable to find the rabbitmq server.
The previous commit ensures that configure-rabbitmq is re-run after
the nodename has changed. However, rabbitmq needs to be stopped
before `rabbitmq-env.conf` is changed; we use an `onlyif` on an `exec`
to print the warning about the node change, and let the subsequent
config change and notify of the service and configure-rabbitmq to
complete the re-configuration.
`/etc/rabbitmq/rabbitmq-env.conf` sets the nodename; anytime the
nodename changes, the backing database changes, and this requires
re-creating the rabbitmq users and permissions.
Trigger this in puppet by running configure-rabbitmq after the file
changes.
