The test here is pretty basic and only tests nginx, but it should get us
started to write tests for different webservers and different ACME
implementations.

These modules implement a way to test ACME based on a test instance of
Letsencrypt's Boulder service. The service implementation is in
letsencrypt.nix and the second module (resolver.nix) is a support-module
for the former, but can also be used for tests not involving ACME.
The second module provides a DNS server which hosts a root zone
containing all the zones and /etc/hosts entries (except loopback) in the
entire test network, so this can be very useful for other modules that
need DNS resolution.
Originally, I wrote these modules for the Headcounter deployment, but
I've refactored them a bit to be generally useful to NixOS users. The
original implementation can be found here:
https://github.com/headcounter/deployment/tree/89e7feafb/modules/testing
Quoting parts from the commit message of the initial implementation of
the Letsencrypt module in headcounter/deployment@95dfb31110:
This module is going to be used for tests where we need to
impersonate an ACME service such as the one from Letsencrypt within
VM tests, which is the reason why this module is a bit ugly (I only
care if it's working not if it's beautiful).
While the module isn't used anywhere, it will serve as a pluggable
module for testing whether ACME works properly to fetch certificates
and also as a replacement for our snakeoil certificate generator.
Also quoting parts of the commit where I have refactored the same module
in headcounter/deployment@85fa481b34:
Now we have a fully pluggable module which automatically discovers
in which network it's used via the nodes attribute.
The test environment of Boulder used "dns-test-srv", which is a fake
DNS server that's resolving almost everything to 127.0.0.1. On our
setup this is not useful, so instead we're now running a local BIND
name server which has a fake root zone and uses the mentioned node
attribute to automatically discover other zones in the network of
machines and generate delegations from the root zone to the
respective zones with the primaryIPAddress of the node.
...
We want to use real letsencrypt.org FQDNs here, so we can't get away
with the snakeoil test certificates from the upstream project but
now roll our own.
This not only has the benefit that we can easily pass the snakeoil
certificate to other nodes, but we can (and do) also use it for an
nginx proxy that's now serving HTTPS for the Boulder web front end.
The Headcounter deployment tests are simulating a production scenario
with real IPs and nameservers so it won't need to rely on
networking.extraHost. However in this implementation we don't
necessarily want to do that, so I've added auto-discovery of
networking.extraHosts in the resolver module.
Another change here is that the letsencrypt module now falls back to
using a local resolver, the Headcounter implementation on the other hand
always required to add an extra test node which serves as a resolver.
I could have squashed both modules into the final ACME test, but that
would make it not very reusable, so that's the main reason why I put
these modules in tests/common.

10k staging builds are not yet finished on Hydra (mostly darwin),
but we now have a 20k jobs rebuilding directly on master, so we would
never get to merge this way...
It doesn't look good when the initial admin user is named
"<hash>-gitolite-admin" and the key stored as
"<hash>-gitolite-admin.pub". Instead, make it simply "gitolite-admin"
and "gitolite-admin.pub".

There are currently two ways to build Openstack image. This just picks
best of both, to keep only one!
- Image is resizable
- Cloudinit is enable
- Password authentication is disable by default
- Use the same layer than other image builders (ec2, gce...)
- sysctl is new and never succeeded on i686-linux
> cannot stat /proc/sys/net/core/bpf_jit_enable: No such file or directory
- testing plasma5 on i686 would defeat part of the reason why we ended
supporting i686 (lots of stuff built on Hydra)
Update physlock to a more current version which supports PAM and
systemd-logind. Amongst others, this should work now with the slim
login manager without any additional configuration, because it does
not rely on the utmp mechanism anymore.
The section was strange to read, as the initial example already used
`listOf' which is mentioned in the very first paragraph. Then you read
in a subsection about `listOf' and the exact same example is given
once again.
This file was removed in 6f0b538044, but sufficient care was not taken
to remove all references to it. Without this change, trying to
rebuild nixos fails.
I realize that advanced users like to configure services with Nix
attrsets, but I don't think we should remove the option to use the
(configuration) language provided by upstream.
