https://github.com/NixOS/nixpkgs/pull/88492 flipped some references to
systemctl from config.systemd.package to /run/current-system/systemd/,
which udevRules obviously isn't able resolve.
If we encounter such references, replace them with
config.systemd.package before doing the check.
The `network-link-${i.name}` units raced with other things trying to
configure the interface, or ran before the interface was available.
Instead of running our own set of shell scripts on boot, and hoping
they're executed at the right time, we can make use of udev to configure
the interface *while they appear*, by providing `.link` files in
/etc/systemd/network/*.link to set MACAddress and MTUBytes.
This doesn't require networkd to be enabled, and is populated properly
on non-networkd systems since
https://github.com/NixOS/nixpkgs/pull/82941.
This continues clean-up work done in
https://github.com/NixOS/nixpkgs/pull/85170 for the scripted networking
stack.
The only leftover part of the `network-link-${i.name}` unit (bringing
the interface up) is moved to the beginning of the
`network-addresses-${i.name}` unit.

it does happen that `dnscrypt-proxy` exit when it is unable to
synchronise its resolvers metadata on startup. this can happen due
to network connectivity issues for example. not restarting it automatically
means no dns resolution will work until a manual restart is performed.
Favor the configuration in "configFile" over "config" to allow
"configFile" to override "config" without a system rebuild.
Add a "persistentKeys" option to generate keys and addresses that
persist across service restarts. This is useful for self-configuring
boot media.
This ensures a correct DBUS_SESSION_BUS_ADDRESS environment variable
is set and imported into the systemd user environment.
Previously this would refer to a non-existing path preventing commands
interacting with the systemd manager from working.
Closes #87502
Also, remove the dangling systemd.services.systemd-binfmt.wants = [
"proc-sys-fs-binfmt_misc.mount" ]; in systemd.nix.
If boot.binfmt.registrations != {}, systemd will install
proc-sys-fs-binfmt_misc.automount, which will auto-mount
`/proc/sys/fs/binfmt_misc` as soon as systemd-binfmt tries to access it.

The 6.0 changelog notes that systemd support was rewritten. The effects
of that seem to be twofold:
* Redis will silently fail to sd_notify if not built with libsystemd,
breaking our unit configuration.
* It also appears to misbehave if told to daemonize when running under
systemd -- note that upstream's sample unit configuration does not
daemonize:

Currently, sudo doesn't work in a NixOS container running inside a Nix
build, because Nix's seccomp filter doesn't allow setuid programs. In
any case, runuser is a bit lower-overhead than sudo.
