The networkd backend logic for setting DHCP= on an interface is bugged
and inconsistent with the scripted logic. Consider this simple NixOS
configuration:
{
networking.useNetworkd = true;
networking.interfaces.eth0.wakeOnLan.enable = true;
}
The default value of networking.useDHCP is true, so we expect our eth0
interface to have DHCP enabled. With the scripted backend, this works.
But the networkd backend generates the following 40-eth0.network file:
[Match]
Name=eth0
[Network]
DHCP=no
IPv6PrivacyExtensions=kernel
This is happening because the wakeOnLan configuration creates a key in
networking.interfaces, and the networkd backend erroneously checks that
instead of for explicitly configured IP addresses as in the scripted
backend. The documentation is also inconsistent across various options.
This change aligns the networkd backend and option documentation to the
actual behavior of the scripted backend, and updates a test to account
for this behavior for both backends.
[Motivation](https://github.com/NixOS/nixpkgs/issues/257817#issuecomment-1741705042):
- Having all the XKB options in the same attribute set clarifies their
relation better than using a common option name prefix ("xkb").
- `services.xserver.layout` is an XKB option, but this is not obvious
from its name. Putting it with the other XKB options clarifies this.

Adds easily overrideable settings for the most common PAM argument
styles. These are:
- Flag (e.g. "use_first_pass"): rendered for true boolean values. false
values are ignored.
- Key-value (e.g. "action=validate"): rendered for non-null, non-boolean
values.
Most PAM arguments can be configured this way. Others can still be
configured with the 'args' option.
Add new test to check if kubo.passthru.repoVersion is set correctly.
Also split the existing NixOS VM test into two independent parts. The test already used two independent VMs but just one testScript. This made experimenting with just one of the two VMs slower than it needed to be. It should also increase parallelism slightly since both test scripts can now run at the same time.
When listening on unix sockets, it doesn't make sense to specify a port
for nginx's listen directive.
Since nginx defaults to port 80 when the port isn't specified (but the
address is), we can change the default for the option to null as well
without changing any behaviour.
The logic for configuring a gateway without an interface specified adds
a route with Gateway= to *every interface* configured by NixOS for
networkd. This leads to nonsensical configurations like the following:
[Network]
DHCP=no
Address=192.168.0.1/24
[Route]
Gateway=10.0.0.1
GatewayOnLink=false
We remove this logic and make defaultGateway.interface required to
configure a default gateway when using networkd.
We can ignore the removal of GatewayOnLink because systemd defaults it
to "no" anyway.
