/etc/hostname is the file used by hostnamectl(1) and the
org.freedesktop.hostname1 dbus service (both provided by systemd) to get
the "static hostname". Better provide it so that users of those
tools/services get a proper hostname.
An example of an issue created by the lack of /etc/hostname is that the
bluetooth stack on NixOS identifies itself to peers as "BlueZ $VERSION"
instead of the hostname.

Changes v1 -> v2:
* ensure /etc/hostname ends with a newline
The test starts the glance service, creates a nixos image and ensures Glance
list it.
Note the test also starts the Keystone service since it is required
by Glance.
* fix/asterisk-module: use unix-group for asterisk-files
* fix/asterisk-module: add configOption to use some default config-files
* fix/asterisk-module: correction of skel copy
* fix/asterisk-module: use /etc/asterisk as configDir
* fix/asterisk-module: add reload; do not restart unit
* asterisk: 13.6.0 -> 14.1.2
* fix/asterisk: compile with lua, pjsip, format_mp3
* fix/asterisk: fix indentation
* fix/asterisk: remove broken flag
The profile minimal has several drawbacks: no man pages, unusual 'dbus'
lib that makes many X11 pieces to rebuild, etc.
With xz compression in the squashfs, despite these additions, the iso is
smaller than what it was in 16.09.
It seems that it is a GPL violation to distribute zfs in the
installation ISOs.

If anyone knows the issue better and has a reason to reenable it
legally, feel free to reenable it. I don't know much about it.
The current default value of listenAddress = null blows up:
$ nixos-rebuild build
error: cannot coerce null to a string, at
.../nixpkgs/nixos/modules/services/monitoring/prometheus/alertmanager.nix:97:16
With listenAddress = "" we use the same default as upstream and there is
no blow up :-)
...by providing a default value of "no labels" (an empty attrset).
Without this change we get
$ nixos-rebuild test -I nixpkgs=.
building Nix...
building the system configuration...
error: The option `services.prometheus.scrapeConfigs.[definition 1-entry 1].static_configs.[definition 1-entry 1].labels' is used but not defined.
which is unneeded, because labels _are_ optional.
All the new options in detail:
Enable docker in multi-user.target make container created with restart=always
to start. We still want socket activation as it decouples dependencies between
the existing of /var/run/docker.sock and the docker daemon. This means that
services can rely on the availability of this socket. Fixes#11478#21303
wantedBy = ["multi-user.target"];
This allows us to remove the postStart hack, as docker reports on its own when
it is ready.
Type=notify
The following will set unset some limits because overhead in kernel's ressource
accounting was observed. Note that these limit only apply to containerd.
Containers will have their own limit set.
LimitNPROC=infinity
LimitCORE=infinity
TasksMax=infinity
Upgrades may require schema migrations. This can delay the startup of dockerd.
TimeoutStartSec=0
Allows docker to create its own cgroup subhierarchy to apply ressource limits on
containers.
Delegate=true
When dockerd is killed, container should be not affected to allow
`live restore` to work.
KillMode=process
currently services.nginx does not start up if `networking.enableIPv6 = false`
the commit changes the nginx behavior to handle this case accordingly.
The commit resolves#21308
The use of unionfs-fuse (57a0f140643cde409022e297ed05e05f8d34d778)
slows down the KDE 5 test enough that it hits Hydra timeouts. (E.g. on
my laptop it went from ~5 min to ~30 min.) So disable it for the KDE
test.

(cherry picked from commit 3fcbcf25568cd629644a680562f47762d1ae15b2)
Overlayfs is quite a bit faster, e.g. with it the KDE 5 test takes ~7m
instead of ~30m on my laptop (which is still not great, since plain
9pfs is ~4m30s).
The structured options are incomplete compared to upstream and I think
it will be a maintenance burden to try to keep up. Instead, provide an
option for the raw config file contents (prometheus.yml).
Ensure that archive members are added in sorted order with a fixed
mtime. This allows `nix-build --check` to succeed (when building a
tarball of a simple system configuration).
We also remove env-vars which doesn't appear to do much apart from
capture a bunch of store paths we probably don't want.
This is an alternative to
4b78a5b5fb
This works around:
machine: must succeed: nix-store -qR /run/current-system | grep nixos-
machine# error: changing ownership of path ‘/nix/store’: Invalid argument
Probably Nix shouldn't be anal about the ownership of the store unless
it's trying to build/write to the store.

(cherry picked from commit 57a0f140643cde409022e297ed05e05f8d34d778)
Previously we were using two or three (qemu_kvm, qemu_test, and
qemu_test with a different dbus when minimal.nix is included).
