* Content of `programlisting` shouldn't be indented, otherwise it's
weirdly indented in the output.
* Use `<xref linkend=.../>` in the release notes: then users can
directly go to the option documentation when reading release notes.
* Don't use docbook tags in `mkRemovedOptionModule`: it's only used
during evaluation where docbook isn't rendered.
For the same reason Alertmanager supports environmentFile to pass
secrets along, it is useful to support the same for Prometheus'
configuration to store bearer tokens outside the Nix store.
The format of the listenAddress option was recently changed to separate
the address and the port parts. There is now a legacy check that
tells users to update to the new format. This legacy check produces
a false positive on IPv6 addresses, since they contain colons.
Fix the regex to make it not match colons within IPv6 addresses.
systemd.exec(5) on DynamicUser:
> If a statically allocated user or group of the configured name

Using DynamicUser while still setting a group name can be
useful for granting access to resources that can otherwise only be
accessed with entirely static IDs.
The postfix exporter needs to access postfix's `queue/public/` directory
to read the `showq` socket inside. Instead of making the public
directory world accessible, this sets the postfix exporter's group to
`postdrop` by default, when the postfix service is enabled.
Accessing the configured port of a service is quite useful, for example
when configuring virtual hosts for a service. The prometheus module did
not expose the configured por separately, making it unnecessarily
cumbersome to consume.
This is a breaking change only if you were setting `listenAddress` to
a non-standard value. If you were, you should now set `listenAddress`
and `port` separately.
If the host network stack is slow to start, the alertmanager fails to
start with this error message:
caller=main.go:256 msg="unable to initialize gossip mesh" err="create memberlist: Failed to get final advertise address: No private IP address found, and explicit IP not provided"
This bug can be reproduced by shutting down the network stack and
restarting the alertmanager.
Note I don't know why I didn't hit this issue with previous
alertmanager releases.
- Fix misspelled option. mkRenamedOptionModule is not used because the
option hasn't really worked before.
- Add missing cfg.telemetryPath arg to ExecStart.
- Fix mkdir invocation in test.
