This is a good example of a package/module that should be distributed
externally (e.g. as a flake [1]): it's not stable yet so anybody who
seriously wants to use it will want to use the upstream repo. Also,
it's highly specialized so NixOS is not really the right place at the
moment (every NixOS module slows down NixOS evaluation for everybody).

It seems that dnsdist doesn't actually request CAP_NET_BIND_SERVICE, which is why normally it's executed and root and setuids to another, unprivileged, user. This means that as it is, dnsdist will be unable to bind to any port under 1024 and will fail with access denied.
Removing CAP_SETGID and CAP_SETUID is also related to this as we don't actually change the uid or gid after the fact as we use DynamicUser. (That part isn't strictly NEEDED but there's no reason to have those capabilities if we don't use them).
There are also some additional sandboxing we can remove from the service definition as they are assumed true or strict by DynamicUser: specifically PrivateTmp and ProtectSystem respectively.
ProtectHome is still there, despite being assumed read-only as setting it to true means they are seen as empty. I don't think it really matters as I don't know if systemd will ignore it or not, but I didn't see any reason to go hunting for excuses to make it a bigger change.
This option was removed because allowing (multiple) regular users to
override host entries affecting the whole system opens up a huge attack
vector. There seem to be very rare cases where this might be useful.
Consider setting system-wide host entries using networking.hosts,
provide them via the DNS server in your network, or use
networking.networkmanager.appendNameservers to point your system to
another (local) nameserver to set those entries.
Otherwise connecting simply fails:
VPN connection: failed to connect: 'La création du fichier « /tmp/lib/NetworkManager-fortisslvpn/0507e3ef-f0e0-4153-af64-b3d9a025877c.config.XSB19Z » a échoué : No such file or directory'
This fixes a regression from bb649d96b0.
There were permission problems, when the preStart script tried to copy
the smokeping.fcgi file over the old file.
This introduces an option wifi.backend to the networkmanager module.

Resolves#66650
These are the leftovers of an older PR.
a. Send messages to auditd if auditing is enabled.
b. Add missing dbus configuration if dnsmasq is used for DNS
Fixes problems such as:
systemd[1]: Failed to put bus name to hashmap: File exists
systemd[1]: dbus-org.freedesktop.nm-dispatcher.service: Two services allocated for the same bus name org.freedesktop.nm_dispatcher, refusing operation.
Problem is that systemd treats symlinks to files outside the service
path differently, causing our old workaround to look like two separate services.
These symlinks are intended to be a means for manually emulating
the behavior of the `Alias=` directive in these services.
Unfortunately even making these symlinks relative isn't enough,
since they don't make it to where it matters--
that only makes the links in /etc/static/systemd/system/*
relative, with systemd still being shown non-relative links
in /etc/systemd/system/*.
To fix this, drop all of this at the package level
and instead simply specify the aliases in the NixOS modules.
Also handle the same for modemmanager,
since the networkmanager NixOS module also handles that.

This option was added in 6336048c58 but it
is essentially a complete duplicate of the existing cfg.servers and
there seems to be no reason to keep maintaining it.
Furthermore, it requires annoying duplication if you try to do option
merging, e.g. merging in sets into your configuration.nix that add
`services.chrony.initstepslew` options will overwrite the servers option
unless you keep it, but that means you just have to duplicate
config.networking.timeServers again anyway which is an implementation
detail!

'iburst' allows chrony to make very quick adjustments to the clock by
doing a couple rapid measurements outside of the default 'minpoll'
option. This helps improve rapid time adjustment at boot, and is enabled
by default.

This is reckless, ill-advised, pointless, and I will be scorned for it,
but it makes me feel a lot better.

Since https://github.com/NixOS/nixpkgs/pull/61321, local-fs.target is
part of sysinit.target again, meaning units without
DefaultDependencies=no will automatically depend on it, and the manual
set dependencies can be dropped.
The `keys.target` is used to indicate whether all NixOps keys were
successfully uploaded on an unattended reboot. However this can cause
startup issues e.g. with NixOS containers (see #67265) and can block
boots even though this might not be needed (e.g. with a dovecot2
instance running that doesn't need any of the NixOps keys).
As described in the NixOps manual[1], dependencies to keys should be
defined like this now:
``` nix
{
systemd.services.myservice = {
after = [ "secret-key.service" ];
wants = [ "secret-key.service" ];
};
}
```
However I'd leave the issue open until it's discussed whether or not to
keep `keys.target` in `nixpkgs`.

When NetworkManager is configured to not manage all interfaces, it's
perfectly fine to have the rest be managed by the standard nixos
wireless scripts.
I use
networking.networkmanager.unmanaged = [
"*" "except:type:wwan" "except:type:gsm"
];
to control everything using networking.wireless except for the mobile
LTE modem which only works with NetworkManager.
The following configuration generates a systemd unit that doesn't
start.
```nix
{
services.syncthing = {
enable = true;
user = "my-user";
};
}
```
It fails with
```
systemd[1]: Started Syncthing service.
systemd[6745]: syncthing.service: Failed to determine group credentials: No such process
systemd[6745]: syncthing.service: Failed at step GROUP spawning /nix/store/n1ydz3i08nqp1ajc50ycy1zribmphqc9-syncthing-1.1.4-bin/bin/syncthing: No such process
systemd[1]: syncthing.service: Main process exited, code=exited, status=216/GROUP
systemd[1]: syncthing.service: Failed with result 'exit-code'.
```
This is due to the fact that `syncthing` group (default) is not
created if the user is overridden.
Add a separate check for setting up the default group, so that
user/group are created independently.
This is a refactor of how resolvconf is managed on NixOS. We split it
into a separate service which is enabled internally depending on whether
we want /etc/resolv.conf to be managed by it. Various services now take
advantage of those configuration options.
We also now use systemd instead of activation scripts to update
resolv.conf.
NetworkManager now uses the right option for rc-manager DNS
automatically, so the configuration option shouldn't be exposed.
We were already creating a group for the user under which to run syncthing but
we were defaulting to running as `nogroup`.
Additionally, use `install` instead of multiple calls to mkdir/cp/chown.
Add an option to set the rc-manager parameter in NetworkManager.conf,
which controls how NetworkManager handles resolv.conf. This sets the
default rc-manager to "resolvconf", which solves #61490. It
additionally allows the user to change rc-manager without interference
from configuration activations.
Applies OpenWRT's noscan patch to hostapd and the relevant option to
the hostapd module.
This noscan patch adds a new `noscan` option allowing us to create
some overlapping BSSs in HT40+/- mode.
Note: this option is disabled by default, we leave this up to the end
user whether it should be enabled or not.
Not being able to create those overlapping BSSs is basically
preventing us to use 802.11n in any urban area where chances to
overlap with another SSID are extremely high.
The patch we are using is a courtesy of the openwrt team and is
applied to the defaul hostapd package in both OpenWRT and Archlinux.
The the extraConfig variable is added below the domain variable in the
ddclient config file. The domain variable should always be last.
