Since all options controlled by the config.php parameters can now be overridden directly, there's no reason to keep them around.

Grafana is now built without support for phantomjs by default. Phantomjs support has been
|
|
<link xlink:href="https://grafana.com/docs/grafana/latest/guides/whats-new-in-v6-4/">deprecated in Grafana</link>
|
|
and the <package>phantomjs</package> project is
|
|
<link xlink:href="https://github.com/ariya/phantomjs/issues/15344#issue-302015362">currently unmaintained</link>.
|
|
It can still be enabled by providing <literal>phantomJsSupport = true</literal> to the package instanciation:
|
|
<programlisting>{
|
|
services.grafana.package = pkgs.grafana.overrideAttrs (oldAttrs: rec {
|

phantomJsSupport = false;

is 20.09 or higher. It also enables number of
|
|
<link xlink:href="https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Sandboxing">systemd sandboxing options</link>

which may possibly interfere with some plugins. If this is the case you can disable the options through attributes in

The initrd SSH support now uses OpenSSH rather than Dropbear to
|
|
allow the use of Ed25519 keys and other OpenSSH-specific

functionality. Host keys must now be in the OpenSSH format, and at
|
|
least one pre-generated key must be specified.

If you used the <option>boot.initrd.network.ssh.host*Key</option>

options, you'll get an error explaining how to convert your host
|
|
keys and migrate to the new
|
|
<option>boot.initrd.network.ssh.hostKeys</option> option.
|

Otherwise, if you don't have any host keys set, you'll need to
|
|
generate some; see the <option>hostKeys</option> option

documentation for instructions.

Since this release there's an easy way to customize your PHP
|
|
install to get a much smaller base PHP with only wanted
|
|
extensions enabled. See the following snippet installing a
|
|
smaller PHP with the extensions <literal>imagick</literal>,
|
|
<literal>opcache</literal>, <literal>pdo</literal> and
|
|
<literal>pdo_mysql</literal> loaded:
|
|
|
|
<programlisting>
|
|
environment.systemPackages = [
|
|
(pkgs.php.withExtensions
|
|
({ all, ... }: with all; [
|
|
imagick
|
|
opcache
|
|
pdo
|
|
pdo_mysql
|
|
])
|
|
)
|
|
];</programlisting>
|
|
|
|
The default <literal>php</literal> attribute hasn't lost any
|
|
extensions. The <literal>opcache</literal> extension has been
|
|
added.
|
|
|
|
All upstream PHP extensions are available under <package><![CDATA[php.extensions.<name?>]]></package>.
|
|
</para>
|

All PHP <literal>config</literal> flags have been removed for
|
|
the following reasons:
|
|
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>
|
|
The updated <literal>php</literal> attribute is now easily
|
|
customizable to your liking by using
|
|
<literal>php.withExtensions</literal> or
|
|
<literal>php.buildEnv</literal> instead of writing config files
|
|
or changing configure flags.
|
|
</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>
|
|
The remaining configuration flags can now be set directly on
|
|
the <literal>php</literal> attribute. For example, instead of
|
|
|
|
<programlisting>
|
|
php.override {
|
|
config.php.embed = true;
|
|
config.php.apxs2 = false;
|
|
}
|
|
</programlisting>
|
|
|
|
you should now write
|
|
|
|
<programlisting>
|
|
php.override {
|
|
embedSupport = true;
|
|
apxs2Support = false;
|
|
}

Deluge 2.x was added and is used as default for new NixOS

installations where stateVersion is >= 20.09. If you are upgrading from a previous

NixOS version, you can set <literal>service.deluge.package = pkgs.deluge-2_x</literal>
|

to upgrade to Deluge 2.x and migrate the state to the new format.

Be aware that backwards state migrations are not supported by Deluge.
