See <link xlink:href="https://github.com/NixOS/nixpkgs/issues/45785">#45785</link> for details. + </para> + <para> + All services should use <xref linkend="opt-systemd.services._name_.startLimitIntervalSec" /> or <literal>StartLimitIntervalSec</literal> in <xref linkend="opt-systemd.services._name_.unitConfig" /> instead. + </para> + </listitem> + <listitem> + <para> + 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> + + <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. + </para> + + <para> + 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. + </para> + </listitem> + <listitem> + <para> + NixOS now defaults to the unified cgroup hierarchy (cgroupsv2). + See the <link xlink:href="https://www.redhat.com/sysadmin/fedora-31-control-group-v2">Fedora Article for 31</link> + for details on why this is desirable, and how it impacts containers. + </para> + <para> + If you want to run containers with a runtime that does not yet support cgroupsv2, + you can switch back to the old behaviour by setting + <xref linkend="opt-systemd.enableUnifiedCgroupHierarchy"/> = <literal>false</literal>; + and rebooting. + </para> + </listitem> + </itemizedlist> + </section> +</section> |
