I was under the impression that setting `services.redis.servers.<name>.save = []` would disable RDB persistence as no schedule would mean no persistence. However since the code did not handle this case specially it actually results in no `save` setting being written and the internal Redis default is used.
This patch handles the empty case to disable RDB persistence.
Disabling RDB persistence is useful in a number of scenarios:
1. Using Redis in a pure-cache mode where persistence is not desired.
2. When using the (generally superior) AOF persistence mode this file is never read so there is little point to writing it.
3. When saving is handled manually
For more information see https://redis.io/docs/manual/persistence/
This is a breaking change as the user may have been relying on `[]` using Redis defaults. However I believe that updating the behaviour for the next release is beneficial as IMHO it is less surprising and does what the user would expect. I have added release notes to warn about this change.
* nixos/vault: add option to start in dev mode.
This is not only useful for nixos tests i.e. when testing vault agent
setups but also when playing around with vault in local setups. In our
tests we can now make use of this option to test more vault features.
i.e. adding this feature has uncovered the need for a `StateDirectory`.
* Update nixos/modules/services/security/vault.nix

* Update attribute names in code examples (* -> settings.*).
* Use `nix-shell -p` rather than `nix run` because the example won't
work with the current default Nix.
* Update config values for `element-web`.
* Fix link to `element-web` security considerations.
* Make the synapse expression even smaller and use callout-lists to
explain the code.
* Document how to correctly deploy the shared registration secret.

Running `nixos/tests/keepassxc.nix` shows:

machine # [ 18.705390] xsession[985]: /nix/store/2g2jx5c6x3p152wbiijr0rmky7byqivc-xsession: line 13: nn: command not found
```
This garbled bash script runs without `set -o errexit` and thus skips
"\n\n" as invalid command:
```
$ cat -n /nix/store/2g2jx5c6x3p152wbiijr0rmky7byqivc-xsession

fi
...
```
KeePassXC uses it through
`nixos/modules/services/x11/display-managers/default.nix`:
```
...
# Script responsible for starting the window manager and the desktop manager.
xsession = dm: wm: pkgs.writeScript "xsession" ''
#! ${pkgs.bash}/bin/bash
# Legacy session script used to construct .desktop files from
# `services.xserver.displayManager.session` entries. Called from
# `sessionWrapper`.
# Start the window manager.
${wm.start}
# Start the desktop manager.
${dm.start}
...
'';

```
The bogus line was introduced in PR #160752:

desktop manager script: start properly
Adds a missing line feed when X is enabled to the start script name
and the appended if check. Resolves#160735
```
I have not tried to reproduce the original issue and thus don't know
why "\n\n" apparently gets interpreted fine in one place but remains
literal the `xsession` case.
However, using a literal newline must be valid for all cases and
certainly fixes the warning seen in KeePassXC tests.
Furthermore, starting the nix string (`''`) with a newline as usual also
fixes its overall indentation.
This patch follows an upstream commit[1].
Before this patch, if acme module is used, caddy will still use an old
cert even a new one is available. The cause is that without --force
flag, caddy will not reload an unchanged config.
Refer to that commit[1] message for more information.

Seems silly to install this for use with the local server, but to not
configure it to use the local server. Otherwise, out of the box we
just get an error about no server being configured.
- Add a module for the thunar file manager, which depends on the xfconf dbus service, and also has a dbus service and a systemd unit.
- Renames the option services.xserver.desktopManager.xfce.thunarPlugins to programs.thunar.plugins.
Riak have been updated a lot since the version 2.2 (now 3.0.10) but
has seen no updated to the package. This is at this point
a problem forcing us to maintain old versions of erlang.
We would be happy to re accept a newer version of Riak if someone want
to spend the time to set it up.
Use `networking.resolvconf.package` to allow DNS entries to be set using
the system-wide resolver implementation instead of hardcoding systemd or
openresolv.
Extend the tests by adding DNS entries and making one of the peers use
systemd-networkd (hence systemd-resolved).
Also add a few `networkd`-specific settings.
According to https://grafana.com/docs/agent/latest/upgrade-guide/#v0240,
this has been deprecated/moved to -server.http.address and
-server.grpc.address (accepting ip and port) config options in v0.24.0,
and already listens on localhost and not port 80 by default.
According to https://github.com/grafana/agent/pull/1540, -prometheus.*
flages were deprecated in 0.19.0 in favor of the -metrics.*
counterparts. Same applies to `loki` being renamed to `logs`.
I'm not sure if the config file format is still supported (it could be),
but we shouldn't use deprecated configs.
The preStart script for the IPFS service will print parts of the configuration
to stdout (and therefore, the journal) when applying profiles on startup. This
may lead to unwanted disclosure of private information, such as remote pinning
service API keys. Fix by sending stdout to /dev/null.
Make secret replacement more robust and futureproof:
- Allow any attribute in `services.parsedmarc.settings` to be a
secret if set to `{ _secret = "/path/to/secret"; }`.
- Hash secret file paths before using them as a placeholders in the
config file to minimize the risk of conflicting file paths being
replaced instead.

config file to minimize the risk of conflicting file paths being
replaced instead.
Commit 8109d8a set the `StateDirectory=` option of the systemd service
configuration to the value of `cfg.workDir` which is wrong, according
to dasJ [1]. This commit resolves this issue by stripping the
`/var/lib/` prefix from `cfg.workDir`.

On one of the two machines I have running openldap, openldap failed to start due to a "timeout". Increasing the allowed startup delay didn't help.
I noticed the following in logs:
```
openldap.service: Got notification message from PID 5224, but reception only permitted for main PID 5223
```
It turns out that on this machine at least, openldap apparently sends the notification from a non-main process, which means that we need this NotifyAccess setting for systemd to record that it successfully started. Without it, after 30 seconds systemd kills the process because it didn't receive the sd_notify call.
Somehow the other machine I have on nixos running ldap works fine even without this, but I could not figure out what changes the behavior.
Given that AFAIU NotifyAccess still restricts to "from the cgroup of the service", I think this change should be safe.
Apparently since systemd v250 a `ListenStream` in an override file won't
override the unit, but will be appended to a list of socket addresses.
The socket unit fails if two or more addresses have the same port,
probably because two systemd processes try to listen to it at once.
The solution is to add an empty `ListenStream=` to reset all previous
definitions.
Fix#175478.
It is already installed by xdg.icons.enable.
Let’s also enable that option explicitly to prevent users from accidentally
disabling it since GNOME will be severely broken without it.
