Types are now specified for all options.
The fixed uid and gid for the avahi user have been removed
and the user avahi is now in the group avahi.
The the generic opening of the firewall for UDP port 5353 is
now optional, but still defaults to true.
The option `extraServiceFiles` was added to specify avahi
service definitions, which are then placed in `/etc/avahi/services`.
We set stateVersion to `mkDefault 18.03` in
`nixos/modules/testing/test-instrumentation.nix` and in
`modules/installer/cd-dvd/installation-cd-base.nix`.
Accessing the stateVersion in the module system from within the tests
results in the following error:
> The unique option `system.stateVersion' is defined multiple times, in
> `nixpkgs/nixos/modules/installer/cd-dvd/installation-cd-base.nix' and
> `nixpkgs/nixos/modules/testing/test-instrumentation.nix'.
There are other tests that use it as well. Namely the radicale test also
verifies behaviour between state versions is as expected. It switches a
package default value. Others switched on the state directory default.
It seems like having the timesyncd switch as part of every rendered
activationScript might cause this weird error.
Removing this line seems like a reasonable thing to do since we actually
set the default to the very same value in the module system. This line
should have been no-op besides the issue that we've two statements
setting it in this very specific case.
The autoLuks module is not really compatible with the updated systemd
version anymore. We started dropping NixOS specific patches that caused
unwanted side effects that we had to work around otherwise.
This change points users towards the relevant PR and spits out a bit of
information on how to deal with the situation.
Somewhen between systemd v239 and v242 upstream decided to no longer run
a few system services with `DyanmicUser=1` but failed to provide a
migration path for all the state those services left behind.
For the case of systemd-timesync the state has to be moved from
/var/lib/private/systemd/timesync to /var/lib/systemd/timesync if
/var/lib/systemd/timesync is currently a symlink.
We only do this if the stateVersion is still below 19.09 to avoid
starting to have an ever growing activation script for (then) ancient
systemd migrations that are no longer required.
See https://github.com/systemd/systemd/issues/12131 for details about
the missing migration path and related discussion.
With systemd v242 using the `Gateway` attribute of the `[Network]`
section will lead to "onlink" routes on all the device that are matched
by the default configuration (typically all devices) causing multiple
default routes (even on localhost).
We can only avoid that - while keeping our default route option - when
we mark the route as explicitly not on link. Only gateways that are
within a subnet of one of the assigned interface addresses will be
installed into the routing table.
With the systemd update to v242 five lines are not longer sufficient to
verify that the storage was verified. In order to reduce future test
failures increasing it to 10 lines sounds like a sane amount.
The udev rules we are shipping no longer work with systemd v242 and were
remove upstream some time ago. It seems like the entire renaming is now
done in C and not in the udev rules.
mysql already has its socket path hardcoded to to
/run/mysqld/mysqld.sock.
There's not much value in making the pidDir configurable, which also
points to /run/mysqld by default.
We only seem to use `services.mysql.pidDir` in the wordpress startup
script, to wait for mysql to boot up, but we can also simply wait on the
(hardcoded) socket location too.
A much nicer way to accomplish that would be to properly describe a
dependency on mysqld.service. This however is not easily doable, due to
how the apache-httpd module was designed.
As we don't need to setup data directories from ExecStartPre= scripts
anymore, which required root, but use systemd.tmpfiles.rules instead,
everything can be run as just the mysql user.
define commands like "waiting for the mysql socket to appear" or "setup
initial databases" in a let expression, so the main control flow becomes
more readable.
We need to keep using `RuntimeDirectory=mysqld`, which translates to
`/run/mysqld`, as this is used for the location of the file socket, that
could differ with what is configured via `cfg.pidDir`.
Before, changing any peers caused the entire WireGuard interface to
be torn down and rebuilt. By configuring each peer in a separate
service we're able to only restart the affected peers.
Adding each peer individually also means individual peer
configurations can fail, but the overall interface and all other peers
will still be added.
A WireGuard peer's internal identifier is its public key. This means
it is the only reliable identifier to use for the systemd service.

$ tmux
error creating /run/user/$(id -u)/tmux-1000 (No such file or directory)
/run/user/$UID/ is created by pam_systemd(3) which also populates
XD_RUNTIME_DIR with that value.
Alternatively, TMUX_TMPDIR might simply default to XDG_RUNTIME_DIR
without providing the same directory yet again as default string in
parameter substitution, however such behaviour change is subject to
another patch.
In fact, with `security.polkit.enable = false` systemd_logind(8) fails
to start and /run/user/$UID/ is never created for unprivileged users
in proper login sessions; XDG_RUNTIME_DIR would consequently not be
set either.
Removing the fallback to /run/user/$UID/ would have caused TMUX_TMPDIR
to be empty, which in turn would lead tmux(1) to use /tmp/. This
effectively breaks the idea of isolated sockets entirely while hiding
errors from the user.
The clickshare-csc1 package brings a udev rule file
to grant access to the ClickShare dongle if connected.
This module provides an option to install that rule file.
Only users in the "clickshare" users group have access.
We differentiate between modules and baseModules in the
VM builder for NixOS tests. This way, nesting.children, eventhough
it doesn't inherit from parent, still has enough config to
actually complete the test. Otherwise, the qemu modules
would not be loaded, for example, and a nesting.children
statement would not evaluate.
