This module permits to preload Docker image in a VM in order to reduce
OIs on file copies. This module has to be only used in testing
environments, when the test requires several Docker images such as in
Kubernetes tests. In this case,
`virtualisation.dockerPreloader.images` can replace the
`services.kubernetes.kubelet.seedDockerImages` options.
The idea is to populate the /var/lib/docker directory by mounting qcow
files (we uses qcow file to avoid permission issues) that contain images.
For each image specified in
config.virtualisation.dockerPreloader.images:
1. The image is loaded by Docker in a VM
2. The resulting /var/lib/docker is written to a QCOW file
This set of QCOW files can then be used to populate the
/var/lib/docker:
1. Each QCOW is mounted in the VM
2. Symlink are created from these mount points to /var/lib/docker
3. A /var/lib/docker/image/overlay2/repositories.json file is generated
4. The docker daemon is started.
Setting this variable in the environment of systemd-timedated allows
'timedatectl' to tell if an NTP service is running.
Closes#48917.

As reported by @andir, the regular expressions that match the sandbox
output are no longer matching in the recent Chromium bump as of
bb03fbc2c8.
Instead of a boolean field that determines whether namespace sandboxes
are on, the namespace sandbox is now an enum within "Layer 1 Sandbox".
I've modified the regular expressions accordingly and also ran the test
for the stable branch, which now succeeds.

By default rspamd will look for multiple files in /etc/rspamd/local.d
and /etc/rspamd/override.d to be included in subsections of the merged
final config for rspamd. Most of the config snippets in the official
rspamd documentation are made to these files and so it makes sense for
NixOS to support them and this is what this commit does.
As part of rspamd 1.8.1 support was added for having custom Lua
rules stored in $LOCAL_CONFDIR/rspamd.local.lua which means that it is
now possible for NixOS to support such rules and so this commit also
adds support for this to the rspamd module.
hass will ignore the standard SIGTERM sent by systemd during stop/restart and we
then have to wait for the timeout after which systemd will forcefully kill the
process.
If instead if we send SIGINT, hass will shut down nicely.
There are many issues reported upstream about the inability to shut down/restart
and it is *supposed* to work with SIGTERM but doesn't.
`services.virtualisation.libvirtd.onShutdown` was previously unused.
While suspending a domain on host shutdown is the default, this commit
makes it so domains can be shut down, also.
* run as user 'slurm' per default instead of root
* add user/group slurm to ids.nix
* fix default location for the state dir of slurmctld:
(/var/spool -> /var/spool/slurmctld)
* Update release notes with the above changes
Rationale
---------
Currently, tests are hard to discover. For instance, someone updating
`dovecot` might not notice that the interaction of `dovecot` with
`opensmtpd` is handled in the `opensmtpd.nix` test.
And even for someone updating `opensmtpd`, it requires manual work to go
check in `nixos/tests` whether there is actually a test, especially
given not so many packages in `nixpkgs` have tests and this is thus most
of the time useless.
Finally, for the reviewer, it is much easier to check that the “Tested
via one or more NixOS test(s)” has been checked if the file modified
already includes the list of relevant tests.
Implementation
--------------
Currently, this commit only adds the metadata in the package. Each
element of the `meta.tests` attribute is a derivation that, when it
builds successfully, means the test has passed (ie. following the same
convention as NixOS tests).
Future Work
-----------
In the future, the tools could be made aware of this `meta.tests`
attribute, and for instance a `--with-tests` could be added to
`nix-build` so that it also builds all the tests. Or a `--without-tests`
to build without all the tests. @Profpatsch described in his NixCon talk
such systems.
Another thing that would help in the future would be the possibility to
reasonably easily have cross-derivation nix tests without the whole
NixOS VM stack. @7c6f434c already proposed such a system.
This RFC currently handles none of these concerns. Only the addition of
`meta.tests` as metadata to be used by maintainers to remember to run
relevant tests.
Referencing modulesPath in NixOS configurations can cause evaluation
errors in restricted mode. If used as `${modulesPath}` (as in all
use-sites in nixpkgs) the modules subtree is copied into its own store
path. Access to this path will be forbidden in restricted mode.
Converting to a string solves this issue.
`${builtins.toString modulesPath}` will point to a subdirectory of the
nixpkgs tree out of which evalModules is called.
This change converts modulesPath to a string by default so that the
call-site doesn't have to anymore.
With this option enabled, before creating file/directories/symlinks in baseDir
according to configuration, old occurences of them are removed.
This prevents remainders of an old configuration (libraries, webapps, you name
it) from persisting after activating a new configuration.
100GB breaks cptofs but 50GB is fine and benchmarks shows it takes the same time as building the demo VBox VM with a 10GB disk
+ enabled VM sound output by default
+ set USB controller in USB2.0 mode
+ add manifest file in the OVA as it allows integrity checking on imports
* journald: forward message to syslog by default if a syslog implementation is installed
* added a test to ensure rsyslog is receiving messages when expected
* added rsyslogd tests to release.nix
The nixos-manual service already uses w3m-nographics for a variant that
drops unnecessary junk like various image libraries.
iso_minimal closure (i.e. uncompressed) goes from 1884M -> 1837M.

TrueCrypt has been retired for a while now and the source archive we
pointed to is gone. Moreover the VeraCrypt fork is available, maintained
and fixes issues previous audits found in TrueCrypt.
Rootston is just a reference compositor so it doesn't make that much
sense to have a module for it. Upstream doesn't really like it as well:
"Rootston will never be intended for downstream packages, it's an
internal thing we use for testing." - SirCmpwn [0]
Removing the package and the module shouldn't cause much problems
because it was marked as broken until
886131c243. If required the package can
still be accessed via wlroots.bin (could be useful for testing
purposes).

* Lets container@.service be activated by machines.target instead of
multi-user.target
According to the systemd manpages, all containers that are registered
by machinectl, should be inside machines.target for easy stopping
and starting container units altogether
* make sure container@.service and container.slice instances are
actually located in machine.slice

* Enable Cgroup delegation for nixos-containers
Delegate=yes should be set for container scopes where a systemd instance
inside the container shall manage the hierarchies below its own cgroup
and have access to all controllers.
This is equivalent to enabling all accounting options on the systemd
process inside the system container. This means that systemd inside
the container is responsible for managing Cgroup resources for
unit files that enable accounting options inside. Without this
option, units that make use of cgroup features within system
containers might misbehave
See original commit: https://github.com/NixOS/systemd/commit/a931ad47a8
from the manpage:
Turns on delegation of further resource control partitioning to
processes of the unit. Units where this is enabled may create and
manage their own private subhierarchy of control groups below the
control group of the unit itself. For unprivileged services (i.e.
those using the User= setting) the unit's control group will be made
accessible to the relevant user. When enabled the service manager
will refrain from manipulating control groups or moving processes
below the unit's control group, so that a clear concept of ownership
is established: the control group tree above the unit's control
group (i.e. towards the root control group) is owned and managed by
the service manager of the host, while the control group tree below
the unit's control group is owned and managed by the unit itself.
Takes either a boolean argument or a list of control group
controller names. If true, delegation is turned on, and all
supported controllers are enabled for the unit, making them
available to the unit's processes for management. If false,
delegation is turned off entirely (and no additional controllers are
enabled). If set to a list of controllers, delegation is turned on,
and the specified controllers are enabled for the unit. Note that
additional controllers than the ones specified might be made
available as well, depending on configuration of the containing
slice unit or other units contained in it. Note that assigning the
empty string will enable delegation, but reset the list of
controllers, all assignments prior to this will have no effect.
Defaults to false.
Note that controller delegation to less privileged code is only safe
on the unified control group hierarchy. Accordingly, access to the
specified controllers will not be granted to unprivileged services
on the legacy hierarchy, even when requested.
The following controller names may be specified: cpu, cpuacct, io,
blkio, memory, devices, pids. Not all of these controllers are
available on all kernels however, and some are specific to the
unified hierarchy while others are specific to the legacy hierarchy.
Also note that the kernel might support further controllers, which
aren't covered here yet as delegation is either not supported at all
for them or not defined cleanly.
In this update:
* binaries `ckb` and `ckb-daemon` are renamed to `ckb-next` and `ckb-next-daemon`
* build system changed from qmake to cmake
* the directory searched for animation plugins no longer needs to be patched, as a result of the build system change
* modprobe patch has been bumped, since the source repository layout has changed
* the cmake scripts are quite FHS-centric and require patching to fix install locations
Nixpkgs' channel currently can't move forward so long as there is a
trace in evaluating the top-level arguments. Which means that it isn't
possible to add a warning message to warn users of future package
removal.
So the only way forward appears to be just removing the alias
altogether.

"machine.target" doesn't actually exist, it's misspelled version
of "machines.target". However, the "systemd-nspawn@.service"
unit already has a default dependency on "machines.target"
This was overlooked on a rebase of mine on master, when I didn't realize
that in the time of me writing the znc changes this new option got
introduced.
On AMD hardware with Mesa 18, compton renders some colours incorrectly
when using the glx backend. This patch sets an environmental variable
for compton so colours are rendered correctly.

This breaks with networking backends enabled and
also creates large delays on boot when some services depends
on the network target. It is also not really required
because tinc does create those interfaces itself.

Tor requires ``SOCKSPort 0`` when non-anonymous hidden services are
enabled. If the configuration doesn't enable Tor client features,
generate a configuration file that explicitly includes this disabling
to allow such non-anonymous hidden services to be created (note that
doing so still requires additional configuration). See #48622.
* nat/bind/dhcp.service:
Remove. Those services have nothing to do with a link-level service.
* sys-subsystem-net-devices-${if}.device:
Add as BindsTo dependency as this will make hostapd stop when the
device is unplugged.
* network-link-${if}.service:
Add hostapd as dependency for this service via requiredBy clause,
so that the network link is only considered to be established
only after hostapd has started.
* network.target:
Remove this from wantedBy clause as this is already implied from
dependencies stacked above hostapd. And if it's not implied than
starting hostapd is not required for this particular network
configuration.

NixOS scripts should be kept in the NixOS source tree, not in
pkgs. Moving them around is just confusing and creates unnecessary
code/history churn.
Move all the nixos-* scripts from the nixos distribution as real
packages in the pkgs/ package set.
This allows non-nixos users to run the script as well. For example,
deploying a remote machine with:
nixos-rebuild --target-host root@hostname --build-host root@hostname
A module for security options that are too small to warrant their own module.
The impetus for adding this module is to make it more convenient to override
the behavior of the hardened profile wrt user namespaces.
Without a dedicated option for user namespaces, the user needs to
1) know which sysctl knob controls userns
2) know how large a value the sysctl knob needs to allow e.g.,
Nix sandbox builds to work
In the future, other mitigations currently enabled by the hardened profile may
be promoted to options in this module.
This option represents the ZNC configuration as a Nix value. It will be
converted to a syntactically valid file. This provides:
- Flexibility: Any ZNC option can be used
- Modularity: These values can be set from any NixOS module and will be
merged correctly
- Overridability: Default values can be overridden
Also done:
Remove unused/unneeded options, mkRemovedOptionModule unfortunately doesn't work
inside submodules (yet). The options userName and modulePackages were never used
to begin with
The system variable is used from the (possibly polluted) shell
environment.
This causes nixos-install to fail in a nix-shell because the system
shell variable is automatically set to the current system (e.g.
x86_64-linux).
