0856500f3e nixos/libvirtd-service: fix fail-to-start when no machines are configured
Don't fail to start the libvirtd service just because there are no files
that match the /etc/libvirt/qemu/*.xml pattern.

7809134e29 postgresql: Fix shutdown
Postgres was taking a long time to shutdown.  This is because we were
sending SIGINT to all processes, apparently confusing the autovacuum
launcher.  Instead it should only be sent to the main process (which
takes care of shutting down the others).

The downside is that systemd will also send the final SIGKILL only to
the main process, so other processes in the cgroup may be left behind.
There should be an option for this...

f52f9bf7cd nixos/libvirtd-service: fix for garbage collected emulator paths
libvirtd puts the full path of the emulator binary in the machine config
file. But this path can unfortunately be garbage collected while still
being used by the virtual machine. Then this happens:

Error starting domain: Cannot check QEMU binary /nix/store/z5c2xzk9x0pj6x511w0w4gy9xl5wljxy-qemu-1.5.2-x86-only/bin/qemu-kvm: No such file or directory

Fix by updating the emulator path on each service startup to something
valid (re-scan $PATH).

9ee30cd9b5 Add support for lightweight NixOS containers
You can now say:

  systemd.containers.foo.config =
    { services.openssh.enable = true;
      services.openssh.ports = [ 2022 ];
      users.extraUsers.root.openssh.authorizedKeys.keys = [ "ssh-dss ..." ];
    };

which defines a NixOS instance with the given configuration running
inside a lightweight container.

You can also manage the configuration of the container independently
from the host:

  systemd.containers.foo.path = "/nix/var/nix/profiles/containers/foo";

where "path" is a NixOS system profile.  It can be created/updated by
doing:

  $ nix-env --set -p /nix/var/nix/profiles/containers/foo \
      -f '<nixos>' -A system -I nixos-config=foo.nix

The container configuration (foo.nix) should define

  boot.isContainer = true;

to optimise away the building of a kernel and initrd.  This is done
automatically when using the "config" route.

On the host, a lightweight container appears as the service
"container-<name>.service".  The container is like a regular NixOS
(virtual) machine, except that it doesn't have its own kernel.  It has
its own root file system (by default /var/lib/containers/<name>), but
shares the Nix store of the host (as a read-only bind mount).  It also
has access to the network devices of the host.

Currently, if the configuration of the container changes, running
"nixos-rebuild switch" on the host will cause the container to be
rebooted.  In the future we may want to send some message to the
container so that it can activate the new container configuration
without rebooting.

Containers are not perfectly isolated yet.  In particular, the host's
/sys/fs/cgroup is mounted (writable!) in the guest.

57f145a7f8 When setting $NIX_REMOTE, check whether /nix/var/nix/db is writable
In NixOS containers, root doesn't have write permission to
/nix/var/nix/db, so it has to use the daemon.

2b0aea1793 Allow running NixOS services outside of systemd
The attribute ‘config.systemd.services.<service-name>.runner’
generates a script that runs the service outside of systemd.  This is
useful for testing, and also allows NixOS services to be used outside
of NixOS.  For instance, given a configuration file foo.nix:

  { config, pkgs, ... }:

  { services.postgresql.enable = true;
    services.postgresql.package = pkgs.postgresql92;
    services.postgresql.dataDir = "/tmp/postgres";
  }

you can build and run PostgreSQL as follows:

  $ nix-build -A config.systemd.services.postgresql.runner -I nixos-config=./foo.nix
  $ ./result

This will run the service's ExecStartPre, ExecStart, ExecStartPost and
ExecStopPost commands in an appropriate environment.  It doesn't work
well yet for "forking" services, since it can't track the main
process.  It also doesn't work for services that assume they're always
executed by root.

b9f5b880e7 nixos/libvirtd-service: fix for dnsmasq (dir perms 700 -> 755)
Fixes this:

Nov 09 16:18:54 nixos-laptop systemd[1]: Starting Libvirt Virtual Machine Management Daemon...
Nov 09 16:18:54 nixos-laptop dnsmasq[15809]: read /etc/hosts - 2 addresses
Nov 09 16:18:54 nixos-laptop dnsmasq[15809]: failed to load names from /var/lib/libvirt/dnsmasq/default.addnhosts: Permission denied
Nov 09 16:18:54 nixos-laptop dnsmasq[15809]: cannot read /var/lib/libvirt/dnsmasq/default.hostsfile: Permission denied
Nov 09 16:18:55 nixos-laptop systemd[1]: Started Libvirt Virtual Machine Management Daemon.

I don't understand the reason for the original 700 permission bits.
Apparently read-access is needed and Ubuntu also use 755 perms.

Use "chmod" instead of "mkdir -m" to set permissions because mkdir doesn't
modify permissions on existing directories.

dc352536a8 nixos: capitalize a bunch of service descriptions
(systemd service descriptions that is, not service descriptions in "man

Capitalizing each word in the description seems to be the accepted
standard.

Also shorten these descriptions:
 * "Munin node, the agent process" => "Munin Node"
 * "Planet Venus, an awesome ‘river of news’ feed reader" => "Planet Venus Feed Reader"
