Eelco Dolstra 1ad9a654be Make starting a container synchronous
So now "systemctl start container@foo" will only return after the
container has reached multi-user.target.

Eelco Dolstra ba88db3cd3 Add support for imperative container management
The command nixos-container can now create containers.  For instance,
the following creates and starts a container named ‘database’:

  $ nixos-container create database

The configuration of the container is stored in
/var/lib/containers/<name>/etc/nixos/configuration.nix.  After editing
the configuration, you can make the changes take effect by doing

  $ nixos-container update database

The container can also be destroyed:

  $ nixos-container destroy database

Containers are now executed using a template unit,
‘container@.service’, so the unit in this example would be
‘container@database.service’.

Eelco Dolstra 2ace7edb81 Rename systemd.containers -> containers
That NixOS containers use systemd-nspawn is just an implementation
detail (which we could change in the future).

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 ac215779dd Give containers a writable /nix/var/nix/{profiles,gcroots}
These are stored on the host in
/nix/var/nix/{profiles,gcroots}/per-container/<container-name> to
ensure that container profiles/roots are not garbage-collected.

Eelco Dolstra ef8e0266a2 Don't reboot a container when its configuration changes

Eelco Dolstra 28b7d67d08 httpd: Don't require keys.target
This has the unintended side-effect of restarting httpd every time we
run switch-to-configuration, even if httpd hasn't changed (because
we're doing a "stop keys.target" now).  So use a "Wants" dependency
instead.

Eelco Dolstra 0d506aa712 Provide a simple way to log into containers
On the host, you can run

  $ socat unix:<path-to-container>/var/lib/login.socket -,echo=0,raw

to get a login prompt.  So this allows logging in even if the
container has no SSH access enabled.

You can also do

  $ socat unix:<path-to-container>/var/lib/root-shell.socket -

to get a plain root shell.  (This socket is only accessible by root,
obviously.)  This makes it easy to execute commands in the container,
e.g.

  $ echo reboot | socat unix:<path-to-container>/var/lib/root-shell.socket -

Eelco Dolstra 1b6c01721d Revert "nixos-manual: show manual on tty8 by default"
This reverts commit b792394119.
Starting the manual on tty8 was intended as a convenience during
installation, not as a general purpose thing.  In fact, given that w3m
runs as root, this is highly insecure!

Duo Security module and uid/gid support for /etc files

Austin Seipp 29d46452dd nixos: add Duo Security module
This module adds the security.duosec attributes, which you can use to
enable simple two-factor authentication for NixOS logins.

The module currently provides PAM and SSH support, although the PAM unix
system configuration isn't automatically dealt with (although the
configuration is automatically built).

Enabling it is as easy as saying:

  security.duosec.ssh.enable = true;
  security.duosec.ikey       = "XXXXXXXX...";
  security.duosec.skey       = "XXXXXXXX...";
  security.duosec.host       = "api-XXXXXXX.duosecurity.com";
  security.duosec.group      = "duosec";

which will enforce two-factor authentication for SSH logins for users in
the 'duosec' group.

This requires uid/gid support in the environment.etc module.

Bjørn Forsman 28e5f72f05 nixos/gpsd-service: change from deprecated 'jobs' type to 'systemd'
This has the nice side-effect of making gpsd actually run!

Old behaviour (debugLevel=2):

  systemd[1]: gpsd.service holdoff time over, scheduling restart.
  systemd[1]: Stopping GPSD daemon...
  systemd[1]: Starting GPSD daemon...
  systemd[1]: gpsd.service start request repeated too quickly, refusing to start.
  systemd[1]: Failed to start GPSD daemon.
  systemd[1]: Unit gpsd.service entered failed state.

New behaviour (debugLevel=2):

  gpsd[945]: gpsd: launching (Version 2.95)
  systemd[1]: Started GPSD daemon.
  gpsd[945]: gpsd: listening on port 2947
  gpsd[945]: gpsd: running with effective group ID 27

Corey O'Connor 40de28afca remove users.jenkins config start on slave config.
Uses standard NixOS user config merging.
Work in progress: The slave config does not actually start the slave agent. This just configures a
jenkins user if required. Bare minimum to enable a nice jenkins SSH slave.

Corey O'Connor 9b79d5b298 Add jenkins continuous integration server and user.
By default the jenkins server is executed under the user "jenkins". Which can be configured using
users.jenkins.* options. If a different user is requested by changing services.jenkins.user then
none of the users.jenkins options apply.

This patch does not include jenkins slave configuration. Some config options will probably change
when this is implemented.

Aspects like the user and environment are typically identical between slave and master. The service
configs are different. The design is for users.jenkins to cover the shared aspects while
services.jenkins and services.jenkins-slave cover the master and slave specific aspects,
respectively.

Another option would be to place everything under services.jenkins and have a config that selects
master vs slave.
