This is a very very very ugly workaround and it's because Chromium seems
to eat keystroke for a few seconds after a new window is created.
I haven't found a better solution yet, so let's at least unbreak the
test until we come up with a better way.
Thanks to @vcunat for bringing this to my attention and also doing the
initial bisect.
The change that brought up this problem was 2b29e40153,
which updated Chromium from version 65.0.3325.181 to version
66.0.3359.117. Unfortunately the upstream changelog[1] is way too large
to actually guess what the breaking change is.

As suggested in https://github.com/NixOS/nixpkgs/pull/39416#discussion_r183845745
the versioning attributes in `lib` should be consistent to
`nixos/version` which implicates the following changes:
* `lib.trivial.version` -> `lib.trivial.release`
* `lib.trivial.suffix` -> `lib.trivial.versionSuffix`
* `lib.nixpkgsVersion` -> `lib.version`
As `lib.nixpkgsVersion` is referenced several times in `NixOS/nixpkgs`,
`NixOS/nix` and probably several user's setups. As the rename will cause
a notable impact it's better to keep `lib.nixpkgsVersion` as alias with
a warning yielded by `builtins.trace`.
mke2fs has this annoying property that it uses getrandom() to get random
numbers (for whatever purposes) which blocks until the kernel's secure
RNG has sufficient entropy, which it usually doesn't in the early boot
(except if your CPU supports RDRAND) where we may need to create the
root disk.
So let's give the VM a virtio RNG to avoid the boot getting stuck at
mke2fs.
Ubiquiti has both a LTS and current version of their Unifi controller software.
The latter adds new features, but may drop support for some devices.
This adds the capability to use either for the unifi module but defaults
to the LTS version, which was the previous behavior.
Previously we indirectly suggested that the user use
services.printing.extraConf to set this, but this doesn't work with the
default merge ordering. Fix this by making it an independent option.
Fixes#39611.
@cleverca found this bug in the declarative hooks config. Any shell
variables referenced in a hook script would get expanded by the hooks
directory builder.
Prevent variable expansion by quoting the here doc limit string.
Allow out of band communication between qemu VMs and the host.
Useful to retrieve IPs of VMs from the host (for instance when libvirt can't analyze
DHCP requests because VMs are configured with static addresses or when
there is connectivity default).
First of all let's start with a clean up the multiline string
indentation for descriptions, because having two indentation levels
after description is a waste of screen estate.
A quick survey in the form of the following also reveals that the
majority of multiline strings in nixpkgs is starting the two beginning
quotes in the same line:
$ find -name '*.nix' -exec sed -n -e '/=$/ { n; /'\'\''/p }' {} + | wc -l
817
$ find -name '*.nix' -exec grep "= *'' *\$" {} + | wc -l
14818
The next point is to get the type, default and example attributes on top
of the description because that's the way it's rendered in the manual.
Most services have their enable option close to the beginning of the
file, so let's move it to the top.
Also, I found the script attribute for dhparams-init.service a bit hard
to read as it was using string concatenation to split a "for" loop.
Now for the more substantial clean ups rather than just code style:
* Remove the "with lib;" at the beginning of the module, because it
makes it easier to do a quick check with "nix-instantiate --parse".
* Use ConditionPathExists instead of test -e for checking whether we
need to generate the dhparams file. This avoids spawning a shell if
the file exists already and it's probably more common that it will
exist, except for the initial creation of course.
* When cleaning up old dhparams file, use RemainAfterExit so that the
unit won't be triggered again whenever we stop and start a service
depending on it.
* Capitalize systemd unit descriptions to be more in par with most
other unit descriptions (also see 0c5e837b66).
* Use "=" instead of "==" for conditionals using []. It's just a very
small nitpick though and it will only fail for POSIX shells. Bash on
the other side accepts it anyway.

This option allows us to turn off stateful generation of Diffie-Hellman
parameters, which in some way is still stateful as the generated DH
params file is non-deterministic.
However what we can avoid with this is to have an increased surface for
failures during system startup, because generation of the parameters is
done during build-time.
Another advantage of this is that we no longer need to take care of
cleaning up the files that are no longer used and in my humble opinion I
would have preferred that #11505 (which puts the dhparams in the Nix
store) would have been merged instead of #22634 (which we have now).
Luckily we can still change that and this change gives the user the
option to put the dhparams into the Nix store.
Beside of the more obvious advantages pointed out here, this also
effects test runtime if more services are starting to use this (for
example see #39507 and #39288), because generating DH params could take
a long time depending on the bit size which adds up to test runtime.
If we generate the DH params in a separate derivation, subsequent test
runs won't need to wait for DH params generation during bootup.
Of course, tests could still mock this by force-disabling the service
and adding a service or activation script that places pre-generated DH
params in /var/lib/dhparams but this would make tests less readable and
the workaround would have to be made for each test affected.
Note that the 'stateful' option is still true by default so that we are
backwards-compatible with existing systems.

We're going to implement an option which allows us to turn off stateful
handling of Diffie-Hellman parameter files by putting them into the Nix
store.
However, modules now might need a way to reference these files, so we
add a now path option to every param specified, which carries a
read-only value of the path where to find the corresponding DH params
file.
I've also improved the description of security.dhparams.params a bit so
that it uses <warning/> and <note/>.
The NixOS VM test also reflects this change and checks whether the old
way to specify the bit size still works.

We're going to make changes to the dhparams module so we really want to
make sure we don't break it, so having a NixOS VM test is to make sure
we don't blow things up and can iterate on it.

Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.
The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:
```
ISA: ARMv8 {-A, -R, -M}
/ \
Mode: Aarch32 Aarch64
| / \
Encoding: A64 A32 T32
```
At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.
The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

xdotool failed in rare cases when a window was already created

I know that "devinfo" output does not currently exist, but so does "devman".
It is mentioned in the nixpkgs manual, but no derivation in nixpkgs actually uses it.
HA doesn't mind the configuration being JSON instead of YAML but since YAML is
the official language, use that as it allows users to easily exchange config
data with other parties in the community.
Additionally, some settings based on NixOS configuation is set via defaultConfig
which is then merged with the user provided configration.
For now that just means http port and time zone but others can easily be added.
This partially reverts a change from e88f28965a
which removed the `mount --rbind /sys`.
While true that the activation scripts will mount `sysfs` at `/sys`,
none of the mountpoints lower in the `/sys` tree are handled by the
activation script, which includes `efivarfs`.
This fixes#38477 since it ensures the presence of `efivarfs` in the
`/sys` tree, which is why the systemd-boot installation failed.
This is more in line with what other services do; also looks cleaner.
It changes configuration entries for pre-and post-hooks type to lines from
lists of strings which are more logical for them; coersion is provided for
backwards compatibility.
Finally, add several steps to improve robustness:
1. Load kernel module on start if not loaded;
2. Don't remove wireguard interface on start; it is removed on service stop. If
it's not something is wrong.
The commit c6f7d43678 changed the system
attribute to be below config.nixpkgs.localSystem, but the test still
uses the old attribute.
I have not tested whether the test actually succeeds but just checked
whether evaluation works and it evaluates successfully now.

Re #38674
This is needed because simp_le expects two certificates in fullchain.pem, leading to error:
> Not enough PEM encoded messages were found in fullchain.pem; at least 2 were expected, found 1.
We now create a CA and sign the key with it instead, providing correct fullchain.pem.
Also cleanup service a bit -- use PATH and a private temporary directory (which
is more suitable).
Do cleanup of user-created additional rules.
Of course it'd be much better to just use iptables-{save,restore} for
declarative management, but as it's still not there...
Introduced in 286b007bd3 and then
in 2e6b796761.
This a proper fix for what 70c6f6572d tried to do.
Removing the "config" prefix triggers the bug on pure nixos too, not only
on nixops.
These don't have affect the default Hydra setup (you need to pass
the relevant system in the supportedSystem list) but let's add it for
completeness and convenience.
Nothing probably uses this, but let's be pedantic and have the
pre-included channel on the install media be as close as possible to
what 'nix-channel --update' will give them.
The only remaining difference is that the channel adds programs.sqlite,
which is fundamentally unfixable.
a) Some providers can update multiple domains - support that.
b) Make "zone" and "script" configurable. Some providers require these.
c) Instead of leaving the ddclient daemon running all the time, use a systemd
timer to kick it off.
d) Don't use a predefined user - run everything via DynamicUser
e) Add documentation
Because it improves out-of-the-box user experience a lot (IMHO).
(zsh completion is already on by default.)
Remove "programs.bash.enableCompletion = true" from
nixos-generate-config.pl, which feels superflous now.
exportReferencesGraph is deprecated and doesn't have the generated
initial Nix database contain the SHA256 of the contents of the store
paths, which breaks various things under Nix 2.0.
Expose the path to a lesskey file as a module option. This makes it
possible to maintain a single lesskey file, used for both NixOS and
non-nix systems. An example of how this can be done follows.
1. Write a derivation that fetches lesskey from a known location:
{ stdenv, fetchgit }:
stdenv.mkDerivation {
name = "foo";
src = fetchgit { .. };
phases = [ "unpackPhase" "installPhase" ];
installPhase = "mkdir -p $out && cp $src/lesskey $out/lesskey";
}
2. Set programs.less.configFile to the corresponding path:
programs.less = {
enable = true;
configFile = "${pkgs.foo}/lesskey";
};
With #36556, a check was introduced to make sure the user and group
names do not exceed their respective maximum length. This is in part
because systemd also enforces that length, but only at runtime.
So in general it's a good idea to catch as much as we can during
evaluation time, however the maximum length of the group name was set to
16 characters according groupadd(8).
The maximum length of the group names however is a compile-time option
and even systemd allows more than 16 characters. In the mentioned pull
request (#36556) there was already a report that this has broken
evaluation for people out there.
I have also checked what other distributions are doing and they set the
length to either 31 characters or 32 characters, the latter being more
common.
Unfortunately there is a difference between the maximum length enforced
by the shadow package and systemd, both for user name lengths and group
name lengths. However, systemd enforces both length to have a maximum of
31 characters and I'm not sure if this is intended or just a off-by-one
error in systemd.
Nevertheless, I choose 32 characters simply to bring it in par with the
maximum user name length.
For the NixOS assertion however, I use a maximum length of 31 to make
sure that nobody accidentally creates services that contain group names
that systemd considers invalid because of a length of 32 characters.

This patch is heavily inspired by bd0d8ed807 which added
a setcap wrapper for `mtr` in order to allow running `mtr` without
`sudo`. The need for the capability `cap_net_raw` that can be registered using
`setcap` has been documented in the Arch Wiki: https://wiki.archlinux.org/index.php/Capabilities#iftop
A simple testcase has been added which starts two machines, one with a
setcap wrapper for `iftop`, one without. Both testcases monitor the
bandwidth usage of the machine using the options `-t -s 1` once, the
machine with setcap wrapper is expected to succeed, the `iftop` on the
machine without setcap wrapper is expected to return a non-zero exit
code.
The `clementine` package is actually released under Apache license, but
requires the unfree `libspotify` package to build.
Now `nixpkgs.clementine` points to the free derivation and
`nixpkgs.clementineUnfree` has been introduced for the package bundled
with spotify support.
