The `keys.target` is used to indicate whether all NixOps keys were successfully uploaded on an unattended reboot. However this can cause startup issues e.g. with NixOS containers (see #67265) and can block boots even though this might not be needed (e.g. with a dovecot2 instance running that doesn't need any of the NixOps keys). As described in the NixOps manual[1], dependencies to keys should be defined like this now: ``` nix { systemd.services.myservice = { after = [ "secret-key.service" ]; wants = [ "secret-key.service" ]; }; } ``` However I'd leave the issue open until it's discussed whether or not to keep `keys.target` in `nixpkgs`.

PostgreSQL now uses

<filename class="directory">/run/postgresql</filename> as its socket
|
|
directory instead of <filename class="directory">/tmp</filename>. So
|
|
if you run an application like eg. Nextcloud, where you need to use

the Unix socket path as the database host name, you need to change it

|
accordingly.

The default resample-method for PulseAudio has been changed from the upstream default <literal>speex-float-1</literal>
|
|
to <literal>speex-float-5</literal>. Be aware that low-powered ARM-based and MIPS-based boards will struggle with this
|
|
so you'll need to set <option>hardware.pulseaudio.daemon.config.resample-method</option> back to <literal>speex-float-1</literal>.

It's now possible to change configuration in

<link linkend="opt-services.nextcloud.enable">services.nextcloud</link> after the initial deploy
|

There exists now <literal>lib.forEach</literal>, which is like <literal>map</literal>, but with
|

arguments flipped. When mapping function body spans many lines (or has nested

<literal>map</literal>s), it is often hard to follow which list is modified.

Previous solution to this problem was either to use <literal>lib.flip map</literal>
|

idiom or extract that anonymous mapping function to a named one. Both can still be used
|

but <literal>lib.forEach</literal> is preferred over <literal>lib.flip map</literal>.
