I think pam_lastlog is the only thing that writes to these files in
practice on a modern Linux system, so in a configuration that doesn't
use that module, we don't need to create these files.
I used tmpfiles.d instead of activation snippets to create the logs.
It's good enough for upstream and other distros; it's probably good
enough for us.
Nix 2.0 no longer uses these directories.
/run/nix/current-load was moved to /nix/var/nix/current-load in 2017
(Nix commit d7653dfc6dea076ecbe00520c6137977e0fced35). Anyway,
src/build-remote/build-remote.cc will create the current-load directory
if it doesn't exist already.
/run/nix/remote-stores seems to have been deprecated since 2014 (Nix
commit b1af336132cfe8a6e4c54912cc512f8c28d4ebf3) when the documentation
for $NIX_OTHER_STORES was removed, and support for it was dropped
entirely in 2016 (Nix commit 4494000e04122f24558e1436e66d20d89028b4bd).
The default value for journald's Storage option is "auto", which
determines whether to log to /var/log/journal based on whether that
directory already exists. So NixOS has been unconditionally creating
that directory in activation scripts.
However, we can get the same behavior by configuring journald.conf to
set Storage to "persistent" instead. In that case, journald will create
the directory itself if necessary.
Previously, the activation script was responsible for ensuring that
/etc/machine-id exists. However, the only time it could not already
exist is during stage-2-init, not while switching configurations,
because one of the first things systemd does when starting up as PID 1
is to create this file. So I've moved the initialization to
stage-2-init.
Furthermore, since systemd will do the equivalent of
systemd-machine-id-setup if /etc/machine-id doesn't have valid contents,
we don't need to do that ourselves.
We _do_, however, want to ensure that the file at least exists, because
systemd also uses the non-existence of this file to guess that this is a
first-boot situation. In that case, systemd tries to create some
symlinks in /etc/systemd/system according to its presets, which it can't
do because we've already populated /etc according to the current NixOS
configuration.
This is not necessary for any other activation script snippets, so it's
okay to do it after stage-2-init runs the activation script. None of
them declare a dependency on the "systemd" snippet. Also, most of them
only create files or directories in ways that obviously don't need the
machine-id set.
environment.sessionVariables cannot refer to the values of env vars,
and as a result this has caused problems in a variety of scenarios.
One use for these is that they're injected into /etc/profile,
elewhere these are used to populate an 'envfile' for pam
(`pam 5 pam_env.conf`) which mentions use of HOME being
potentially problematic.
Anyway if the goal is to make things easier for users,
simply do the NIX_PATH modification as extraInit.
This fixes the annoying problems generated by the current approach
(#40165 and others) while hopefully serving the original goal.
One way to check if things are borked is to try:
$ sudo env | grep NIX_PATH
Which (before this change) prints NIX_PATH variable with
an unexpanded $HOME in the value.
-------
This does mean the following won't contain user channels for 'will':
$ sudo -u will nix-instantiate --eval -E builtins.nixPath
However AFAICT currently they won't be present either,
due to unescaped $HOME. Unsure if similar situation for other users
of sessionVariables (not sudo) work with current situation
(if they exist they will regress after this change AFAIK).
Previously single quotes were used by default for aliases and the module
never warned about possible collisions when having a shell alias which
relies on single quotes.
Adding `escapeShellArg` works around this fixes the issue and ensures that a
properly quoted value is written to `/etc/zshrc`.
The socket activation I added to the rspamd module doesn't actually work
and can't be made to work without changes to rspamd.

Evaluation error introduced in 599c4df46a.
There is only a "platformS" attribute in kexectools.meta, so let's use
this and from the code in the kexec module it operates on a list,
matching the corresponding platforms, so this seems to be the attribute
the original author intended.
Tested by building nixos/tests/kexec.nix on x86_64-linux and while it
evaluates now, the test still fails by timing out shortly after the
kexec:
machine: waiting for the VM to finish booting
machine# Cannot find the ESP partition mount point.
This however seems to be an unrelated issue and was also the case before
the commit mentioned above.

Nix commands inside the container have been broken since 18.03,
and no fix is yet in sight. Lets remove from the documentation
that this is a usecase that we support, as it doesn't seem
likely that this will be fixed before 18.09 either.
See #40355
Changes the evaluation order in that it evaluates assertions before
warnings, so that eg. the following would work:
{ config, lib, ... }:
{
options.foo = lib.mkOption {
type = lib.types.bool;
default = true;
description = "...";
};
options.bar = lib.mkOption {
type = lib.types.bool;
default = false;
description = "...";
};
config = lib.mkMerge [
(lib.mkIf config.bar {
system.build.bar = "foobar";
})
(lib.mkIf config.foo {
assertions = lib.singleton {
assertion = config.bar;
message = "Bar needs to be enabled";
};
systemd.services.foo = {
description = "Foo";
serviceConfig.ExecStart = config.system.build.bar;
};
})
];
}
This is because the systemd module includes definitions for warnings
that would trigger evaluation of the config.system.build.bar definition.
The original pull request references a breakage due to the following:
{
services.nixosManual.enable = false;
services.nixosManual.showManual = true;
}
However, changing the eval order between asserts and warnings clearly is
a corner case here and it only happens because of the aforementioned
usage of warnings in the systemd module and needs more discussion.
Nevertheless, this is still useful because it lowers the evaluation time
whenever an assertion is hit, which is a hard failure anyway.
Introduced by 0f3b89bbed.
If services.nixosManual.showManual is enabled and
documentation.nixos.enable is not, there is no
config.system.build.manual available, so evaluation fails. For example
this is the case for the installer tests.
There is however an assertion which should catch exactly this, but it
isn't thrown because the usage of config.system.build.manual is
evaluated earlier than the assertions.
So I split the assertion off into a separate mkIf to make sure it is
shown appropriately and also fixed the installation-device profile to
enable documentation.nixos.

This breaks evaluation of the tested job:
attribute 'diskInterface' missing, at /nix/store/5k9kk52bv6zsvsyyvpxhm8xmwyn2yjvx-source/pkgs/build-support/vm/default.nix:316:24
Most importantly, this sets PrivateTmp, ProtectHome, and ProtectSystem
so that Chrony flaws are mitigated, should they occur.
Moving to ProtectSystem=full however, requires moving the chrony key
files under /var/lib/chrony -- which should be fine, anyway.
This also ensures ConditionCapability=CAP_SYS_TIME is set, ensuring
that chronyd will only be launched in an environment where such a
capability can be granted.

The test failed on Hydra in one instance because a request to the
server was sent before indexing was finished.
Retry the request until it succeeds (or times out).
This reverts commit 67c8c49177.
'nix run nixos.firefox' is *not* supposed to work - the Nix 2.x
interface attempts to standardize on nixpkgs.*, to get rid of the
nixos/nixpkgs confusion that existed with the channels interface. So
let's not bring that confusion back.
When a bridge interface was reconfigured, running containers using
this bridge lost connectivity: restarting network-addresses-brN.service
triggered a restart of network-setup.service via a "partOf" relationship
introduced in 07e0c0e0a2.
This in turn restarted brN-netdev.service.
The bridge was thus destroyed and recreated with the same name but a new
interface id, causing attached veth interfaces to lose their connection.
This change removes the "partOf" relationship between
network-setup.service and network-addresses-brN.service for all bridges.
Because when I see "config.system.build.manual.manual" after I forgot
what it means I ask "Why do I need that second `.manual` there again?".
Doesn't happen with `config.system.build.manual.manualHTML`.
This is taken from the 18.09 change, which was reverted on release-18.09
but not master. The now-false 18.09 release notes were just removed from
master in 29854e2426, but since the
underlying change is still there, release notes for 19.03 are warranted.
This commit takes the now-reverted release notes and reuses them for
that.
Without this the graphical installer has no way to open the manual.
You can fix it yourself by installing any HTML browser but this might
be unfamiliar to users new to NixOS and without any other way to open
the manual. The downside is it will also increase download sizes.

/run/rmilter is set by systemd, and have root:root ownership, which
prevent pid file to write.
This fix suggested to be promoted to 18.09 branch.
(Although rmilter itself is deprecated, and I plan to remove it, after
18.09 would be released)
Add package libratbag and service module ratbagd
Libratbag contains ratbagd daemon and ratbagctl cli to configure

Add mvnetbiz to maintainers.
The test failed in one run on Hydra, logs look like
dhcpcd changed ipv6 routing at just the wrong time.
Disable dhcpcd. It's not needed, the test uses static IPs anyway.
Test didn't run because it tried to create a VM with 4096M RAM
but qemu-system-i386 has a hard 2047M memory limit.
- reduce memory to 2047M on i686.
- increase timeout 300s -> 1800s because the tests are much slower
on i686 and timed out.
Instead of searching `/usr` it should search for the `xkb`,
$XDG_DATA_DIRS will be searched. With this approach we allow compliance
on NixOS and non-NixOS systems to find `symbols` in the `xkb` directory.
The patch has been accepted by upstream, but isn't released yet, so this
is mainly a temporary fix until we can bump ZSH to the next stable version.
The `xserver` module links `/share/X11/xkb` to `/run/current-system` to
make this possible.
The fix can be tested inside the following VM:
```
{
zshtest = {
programs.zsh.enable = true;
users.extraUsers.vm = {
password = "vm";
isNormalUser = true;
};
services.xserver.enable = true;
};
}
```
Fixes#46025
The `pkgs.yabar` package is relatively old (2016-04) and contains
several issues fixed on master. `yabar-unstable` containsa recent master
build with several fixes and a lot of new features (I use
`yabar-unstable` for some time now and had no issues with it).
In the upstream bugtracker some bugs could be fixed on ArchLinux by
simply installing `yabar-git` (an AUR package which builds a recent
master).
To stabilize the module, the option `programs.yabar.package` now
defaults to `pkgs.yabar-unstable` and yields a warning with several
linked issues that are known on `pkgs.yabar`.
The test has been refactored as well to ensure that `yabar` actually
starts (and avoid non-deterministic random success) and takes a
screenshot of a very minimalistic configuration on IceWM.
Fixes#46899
This test doesn't work in a sandbox and never succeeded on Hydra.
It simulates an EC2 instance reconfiguring itself at runtime,
which needs network access.
This allows the definition of a custom derivation of Exim,
which can be used to enable custom features such as LDAP and PAM support.
The default behaviour remains unchanged (defaulting to pkgs.exim).
This attempts to improve stability of the test by using existing
services for miniupnpd and transmission.
It also uses explicit addresses for the network interfaces so that the
external IP addresses are valid internet addresses (thus fixing
validation problems from upnpc).
Also disable eth0 from being used to transfer torrents over without that
being the intention.
10G is not enough for a desktop installation, and resizing a Virtualbox disk image is a pain.
Let's increase the default disk size to 100G. It does not require more storage space, since the empty bits are left out.

/opt/namespace.yaml missing.
Added release notes with reference to Kubernetes 1.11 release notes.

1. Simplify the command by reading directly from /etc/machine-id which
is already a random, lower-case hex string
2. Previously, the command output could be too short because of missing
leading digits. This is now fixed.
* acquire DHCP on the interfaces with networking.interface.$name.useDHCP == true or on all interfaces if networking.useDHCP == true (was only only "eth0")
* respect "mtu" if it was in DHCP answer (it happens in the wild)
* acquire and set up staticroutes (unlike others clients, udhcpc does not do the query by default); this supersedes https://github.com/NixOS/nixpkgs/pull/41829
For update-mime-database to work, you must have to have some mime

That way the built-in web server is usable by default but users can use
$HOME/web directly (instead of having to use a symlink), if they want to
customize the webpage.
Without a group the gid will default to 65534 (2^16 - 2) which maps to
"nogroup". IMO it makes more sense to explicitly set a valid group.
Adding pkgs.sks to environment.systemPackages is not required (IIRC we
want to avoid bloating environment.systemPackages). Instead it seems
like a better idea to make the relevant binaries available to the user
sks and enable useDefaultShell so that "su -l sks" can be used for
manual interaction (that way the files will always have the correct
owner).
This commit adds the following
* the uucp user
* options for HylaFAX server to control startup and modems
* systemd services for HylaFAX server processes
including faxgettys for modems
* systemd services to maintain the HylaFAX spool area,
including cleanup with faxcron and faxqclean
* default configuration for all server processes
for a minimal working configuration
Some notes:
* HylaFAX configuration cannot be initialized with faxsetup
(as it would be common on other Linux distributions).
The hylafaxplus package contains a template spool area.
* Modems are controlled by faxgetty.
Send-only configuration (modems controlled by faxq)
is not supported by this configuration setup.
* To enable the service, one or more modems must be defined with
config.services.hylafax.modems .
* Sending mail *should* work:
HylaFAX will use whatever is in
config.services.mail.sendmailSetuidWrapper.program
unless overridden with the sendmailPath option.
* The admin has to create a hosts.hfaxd file somewhere
(e.g. in /etc) before enabling HylaFAX.
This file controls access to the server (see hosts.hfaxd(5) ).
Sadly, HylaFAX does not permit account-based access
control as is accepts connections via TCP only.
* Active fax polling should work; I can't test it.
* Passive fax polling is not supported by HylaFAX.
* Pager transmissions (with sendpage) are disabled by default.
I have never tested or used these.
* Incoming data/voice/"extern"al calls
won't be handled by default.
I have never tested or used these.
Take two of #40708 (4fe2898608).
That PR attempted to bidirectionally default `config.nixpkgs.system` and
`config.nixpkgs.localSystem.system` to each be updated by the other. But
this is not possible with the way the module system works. Divergence in
certain cases in inevitable.
This PR is more conservative and just has `system` default `localSystem`
and `localSystem` make the final call as-is. This solves a number of
issues.
- `localSystem` completely overrides `system`, just like with nixpkgs
proper. There is no need to specify `localSystem.system` to clobber the
old system.
- `config.nixpkgs.localSystem` is exactly what is passed to nixpkgs. No
spooky steps.
- `config.nixpkgs.localSystem` is elaborated just as nixpkgs would so
that all attributes are available, not just the ones the user
specified.
The remaining issue is just that `config.nixpkgs.system` doesn't update
based on `config.nixpkgs.localSystem.system`. It should never be
referred to lest it is a bogus stale value because
`config.nixpkgs.localSystem` overwrites it.
Fixes#46320
This adds several improvements the previously introduced
`services.weechat` module:
* Dropped `services.weechat.init` as the initialization script can now
be done on package-level since 2af41719bc using the `configure`
function.
* Added `sessionName` option to explicitly configure a name for the
`screen` session (by default: weechat-screen).
* Added `binary` option to configure the binary name (e.g.
`weechat-headless`).
* Added docs regarding `screen` session and `weechat.service`.
Previously it was only possible to use very simple Riemann config.
For more complicated scenarios you need a directory of clojure
files and the config file that riemann starts with should be in this
directory.
