provided by upstream before upgrading. Worth specifically noting is that the service now runs

entirely as a dedicated <literal>pdns</literal> user, instead of starting as <literal>root</literal>

xfsprogs was update from 4.19 to 5.10. It now enables reflink support by default on filesystem creation.
|
|
Support for reflinks was added with an experimental status to kernel 4.9 and deemed stable in kernel 4.16.
|
|
If you want to be able to mount XFS filesystems created with this release of xfsprogs on kernel releases older than those, you need to format them
|
|
with <literal>mkfs.xfs -m reflink=0</literal>.

The uWSGI server is now built with POSIX capabilities. As a consequence,
|
|
root is no longer required in emperor mode and the service defaults to
|
|
running as the unprivileged <literal>uwsgi</literal> user. Any additional
|
|
capability can be added via the new option
|
|
<xref linkend="opt-services.uwsgi.capabilities"/>.
|
|
The previous behaviour can be restored by setting:
|
|
<programlisting>
|
|
<xref linkend="opt-services.uwsgi.user"/> = "root";
|
|
<xref linkend="opt-services.uwsgi.group"/> = "root";

gid = "uwsgi";

Another incompatibility from the previous release is that vassals running under a

different user or group need to use <literal>immediate-{uid,gid}</literal>

As a result, <literal>extraConfig</literal> and <literal>extraDatabaseConfig</literal>

file to OLC configuration with the following script (find the location of this

Amazon EC2 and OpenStack Compute (nova) images now re-fetch instance meta data and user data from the instance
|
|
metadata service (IMDS) on each boot. For example: stopping an EC2 instance, changing its user data, and

restarting the instance will now cause it to fetch and apply the new user data.

<para>

Specifically, <literal>/etc/ec2-metadata</literal> is re-populated on each boot. Some NixOS scripts that read
|
|
from this directory are guarded to only run if the files they want to manipulate do not already exist, and so
|
|
will not re-apply their changes if the IMDS response changes. Examples: <literal>root</literal>'s SSH key is
|
|
only added if <literal>/root/.ssh/authorized_keys</literal> does not exist, and SSH host keys are only set from
|
|
user data if they do not exist in <literal>/etc/ssh</literal>.

The prometheus json exporter is now managed by the prometheus community. Together with additional features
|
|
some backwards incompatibilities were introduced.
|
|
Most importantly the exporter no longer accepts a fixed command-line parameter to specify the URL of the
|
|
endpoint serving JSON. It now expects this URL to be passed as an URL parameter, when scraping the exporter's
|
|
<literal>/probe</literal> endpoint.
|
|
In the prometheus scrape configuration the scrape target might look like this:
|
|
<programlisting>
|
|
http://some.json-exporter.host:7979/probe?target=https://example.com/some/json/endpoint
|
|
</programlisting>

Documentation is available in the upstream repository and a small example for NixOS is available

in the corresponding NixOS test.

The attribute <varname>mpi</varname> is now consistently used to
|
|
provide a default, system-wide MPI implementation.
|
|
The default implementation is openmpi, which has been used before by
|
|
all derivations affects by this change.
|
|
Note that all packages that have used <varname>mpi ? null</varname> in the input
|
|
for optional MPI builds, have been changed to the boolean input paramater

<varname>useMpi</varname> to enable building with MPI.

NixOS now emits a deprecation warning if systemd's <literal>StartLimitInterval</literal> setting is used in a <literal>serviceConfig</literal> section instead of in a <literal>unitConfig</literal>; that setting is deprecated and now undocumented for the service section by systemd upstream, but still effective and somewhat buggy there, which can be confusing.

The Unbound DNS resolver service (<literal>services.unbound</literal>) has been refactored to allow reloading, control sockets and to fix startup ordering issues.
|
|
</para>
|
|
|
|
<para>
|
|
It is now possible to enable a local UNIX control socket for unbound by setting the <xref linkend="opt-services.unbound.localControlSocketPath" />
|
|
option.

</para>

Previously we just applied a very minimal set of restrictions and
|
|
trusted unbound to properly drop root privs and capabilities.
|
|
</para>
|
|
|
|
<para>
|
|
As of this we are (for the most part) just using the upstream
|
|
example unit file for unbound. The main difference is that we start
|
|
unbound as <literal>unbound</literal> user with the required capabilities instead of
|
|
letting unbound do the chroot & uid/gid changes.
|
|
</para>
|
|
|
|
<para>
|
|
The upstream unit configuration this is based on is a lot stricter with
|
|
all kinds of permissions then our previous variant. It also came with
|
|
the default of having the <literal>Type</literal> set to <literal>notify</literal>, therefore we are now also
|
|
using the <literal>unbound-with-systemd</literal> package here. Unbound will start up,
|
|
read the configuration files and start listening on the configured ports
|
|
before systemd will declare the unit <literal>active (running)</literal>.
|
|
This will likely help with startup order and the occasional race condition during system
|
|
activation where the DNS service is started but not yet ready to answer
|
|
queries. Services depending on <literal>nss-lookup.target</literal> or <literal>unbound.service</literal>
|
|
are now be able to use unbound when those targets have been reached.
|
|
</para>
|
|
|
|
<para>
|
|
Aditionally to the much stricter runtime environmet the
|
|
<literal>/dev/urandom</literal> mount lines we previously had in the code (that would
|
|
randomly failed during the stop-phase) have been removed as systemd will take care of those for us.

The <literal>preStart</literal> script is now only required if we enabled the trust
|
|
anchor updates (which are still enabled by default).
|
|
</para>
|
|
|
|
<para>
|
|
Another benefit of the refactoring is that we can now issue reloads via
|
|
either <literal>pkill -HUP unbound</literal> and <literal>systemctl reload unbound</literal> to reload the
|
|
running configuration without taking the daemon offline. A prerequisite
|
|
of this was that unbound configuration is available on a well known path
|
|
on the file system. We are using the path <literal>/etc/unbound/unbound.conf</literal> as that is the
|
|
default in the CLI tooling which in turn enables us to use
|
|
<literal>unbound-control</literal> without passing a custom configuration location.
