nixos/dhcpcd: Only run resume commands if enabled.
The networkd implementation sets systemd.services.dhcpcd.enable to
false in nixos/modules/tasks/network-interfaces-systemd.nix. So we need
to respect that in the dhcpcd module.

If we don't, the resumeCommand is set nevertheless, which causes the
post-resume.service to fail after resuming:

Failed to reload dhcpcd.service: Unit dhcpcd.service is masked.
post-resume.service: main process exited, code=exited, status=1/FAILURE
Failed to start Post-Resume Actions.
Dependency failed for Post-Resume Actions.
Unit post-resume.service entered failed state.
post-resume.service failed.

Eelco Dolstra 2d8c0d24f2 dhcpcd: Fix segfaults
This fixes several problems in the dhcpcd service:

* A segfault during startup, due to a race with udev (dhcpcd would get
  an ADD event from udev, causing it to re-add an interface that it
  already had, leading to a segfault later on).

* A hang/segfault processing "dhcpcd rebind" (which NixOS calls after
  waking up from suspend).

Also, add "lo" to the list of ignored interfaces. It usually ignores
"lo", but apparently not when it gets an ADD event from udev.

Eelco Dolstra 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.

Jaka Hudoklin 70a4c7b1df nixos: fix linux containers (systemd-nspawn, lxc, lxc-libvirt)
- Make dhcp work, use dhcpcd without udev in container
- Make login shell work, patch getty to not wait for /dev/tty0
- Make ssh work, sshd/pam do not start session

Eelco Dolstra 895bcdd1cb Add support for running a container with a private network interface
For example, the following sets up a container named ‘foo’.  The
container will have a single network interface eth0, with IP address
10.231.136.2.  The host will have an interface c-foo with IP address
10.231.136.1.

  systemd.containers.foo =
    { privateNetwork = true;
      hostAddress = "10.231.136.1";
      localAddress = "10.231.136.2";
      config =
        { services.openssh.enable = true; };
    };

With ‘privateNetwork = true’, the container has the CAP_NET_ADMIN
capability, allowing it to do arbitrary network configuration, such as
setting up firewall rules.  This is secure because it cannot touch the
interfaces of the host.

The helper program ‘run-in-netns’ is needed at the moment because ‘ip
netns exec’ doesn't quite do the right thing (it remounts /sys without
bind-mounting the original /sys/fs/cgroups).

Eelco Dolstra 559f5be07d dhcpcd: Update to 6.2.1
Dhcpcd now has integration with udev, so it should no longer be a
problem if udev renames an interface while dhcpcd is running.

William A. Kennington III 38bc05158d network-interfaces: Add the ability to create bond devices
This patch adds support for the creations of new bond devices, aggregate
pipes of physical devices for extra throughput or failover.

Additionally, add better correction at the startup of a bridge
of vlan interface (delete old, stale interfaces).
