21573af9fb Containers: Use /etc/resolv.conf supplied by the host
This used to work with systemd-nspawn 203, because it bind-mounted
/etc/resolv.conf (so openresolv couldn't overwrite it). Now it's just
copied, so we need some special handling.

e34a1589fe Add support for user units
With ‘systemd.user.units’ and ‘systemd.user.services’, you can specify
units used by per-user systemd instances.  For example,

  systemd.user.services.foo =
    { description = "foo";
      wantedBy = [ "default.target" ];
      serviceConfig.ExecStart = "${pkgs.foo}/bin/foo";
    };

declares a unit ‘foo.service’ that gets started automatically when the
user systemd instance starts, and is stopped when the user systemd
instance stops.

Note that there is at most one systemd instance per user: it's created
when a user logs in and there is no systemd instance for that user
yet, and it's removed when the user fully logs out (i.e. has no
sessions anymore). So if you're simultaneously logged in via X11 and a
virtual console, you get only one copy of foo.

179acfb664 Allow upstream systemd units to be extended
If you define a unit, and either systemd or a package in
systemd.packages already provides that unit, then we now generate a
file /etc/systemd/system/<unit>.d/overrides.conf. This makes it
possible to use upstream units, while allowing them to be customised
from the NixOS configuration. For instance, the module nix-daemon.nix
now uses the units provided by the Nix package. And all unit
definitions that duplicated upstream systemd units are finally gone.

This makes the baseUnit option unnecessary, so I've removed it.

560a1103ad Add option ‘systemd.tmpfiles.rules’
This allows specifying rules for systemd-tmpfiles.

Also, enable systemd-tmpfiles-clean.timer so that stuff is cleaned up
automatically 15 minutes after boot and every day, *if* you have the
appropriate cleanup rules (which we don't have by default).

eda854d50f systemd: Add an assertion to guarantee oneshot units do not have restart set
This prevents insidious errors once systemd begins handling the unit. If
the unit is loaded at boot, any errors of this nature are logged to the
console before the journal service is running. This makes it very hard
to diagnose the issue. Therefore, this assertion helps guarantee the
mistake is not made.

29027fd1e1 Rewrite ‘with pkgs.lib’ -> ‘with lib’
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.

systemd: Add support for path units.
This allows to define systemd.path(5) units, for example like this:

{
  systemd = let
    description = "Set Key Permissions for xyz.key";
  in {
    paths.set-key-perms = {
      inherit description;
      before = [ "network.target" ];
      wantedBy = [ "multi-user.target" ];
      pathConfig.PathChanged = "/run/keys/xyz.key";
    };

    services.set-key-perms = {
      inherit description;
      serviceConfig.Type = "oneshot";
      script = "chown myspecialkeyuser /run/keys/xyz.key";
    };
  };
}

The example here is actually useful in order to set permissions for the
NixOps keys target to ensure those permisisons aren't reset whenever the
key file is reuploaded.

691c0cd72e systemd: Allow customisation of upstream units
You can now say:

  systemd.services.foo.baseUnit = "${pkgs.foo}/.../foo.service";

This will cause NixOS' generated foo.service file to include
foo.service from the foo package.  You can then apply local
customization in the usual way:

  systemd.services.foo.serviceConfig.MemoryLimit = "512M";

Note however that overriding options in the original unit may not
work.  For instance, you cannot override ExecStart.

It's also possible to customize instances of template units:

  systemd.services."getty@tty4" =
    { baseUnit = "/etc/systemd/system/getty@.service";
      serviceConfig.MemoryLimit = "512M";
    };

This replaces the unit options linkTarget (which didn't allow
customisation) and extraConfig (which did allow customisation, but in
a non-standard way).

We used to have the configuration of the kernel available in a

available.  It only eats a few kilobytes.
