This adds the pinns path to the configuration let CRI-O start properly.
We also change the configuration to the new drop-in syntax.

The toplevel derivations of systems that have `networking.hostName`
set to `""` (because they want their hostname to be set by DHCP) used
to be all named
`nixos-system-unnamed-${config.system.nixos.label}`.
This makes them hard to distinguish.
A similar problem existed in NixOS tests where `vmName` is used in the
`testScript` to refer to the VM. It defaulted to the
`networking.hostName` which when set to `""` won't allow you to refer
to the machine from the `testScript`.
This commit makes the `system.name` configurable. It still defaults to:
```
if config.networking.hostName == ""
then "unnamed"
else config.networking.hostName;
```
but in case `networking.hostName` needs to be to `""` the
`system.name` can be set to a distinguishable name.
This is analogous to #70447.
With security.lockKernelModules=true, docker commands result in the following
error without at least loading veth:

This is required by (among others) Podman to run containers in rootless mode.
Other distributions such as Fedora and Ubuntu already set up these mappings.
The scheme with a start UID/GID offset starting at 100000 and increasing in 65536 increments is copied from Fedora.

Without this, systemd-boot does not add an EFI boot entry for itself.
The reason it worked before this fix is because it would fall back to
the default installed \EFI\BOOT\BOOTX64.EFI
boot.loader.grub.device` was hardcoded to `bootDevice`, which is
wrong, because that's the device for `/`, and with `useBootLoader`
the boot loader is not on that device.
This bug probably came into existence because of bad naming;
`virtualisation.bootDevice` has description
"The disk to be used for the root filesystem", which is very confusing;
it should be `.rootDevice` then!
Unfortunately, the description is right and the attribute name is wrong,
so it is not easy to change this without deprecation.
This commit ensures that even if you use `useBootLoader` and
`diskInterface == "scsi"`, the created VM can boot through, and can run
`nixos-rebuild afterwards.
It also adds extra commentary to explain what's going on in this module
in general in relation to `useBootLoader`.
VMSGVA is recommended by virtualbox for Linux clients.
Compared to VBoxVGA and VBoxSVGA it also supports 3D acceleration.
Adding the driver makes nixos work with all three supported graphics card
types.
xchg is advertised as a bidirectional exchange dir, but file content
transfer from host to VM fails due to caching:
If a file is read in the VM and then modified on the host, subsequent
re-reads in the VM can yield old, cached data.
This is caused by the use of 9p's cache=loose mode that is explicitly
meant for read-only mounts.
9p doesn't provide any suitable cache modes, so fix this by disabling
caching.
Also, remove a now unnecessary sync in the test driver.
- Update the default pause image
- Set the cgroup manager to systemd
- Enable `manage_ns_lifecycle` instead of the deprecated
`manage_network_ns_lifecycle` option

This follows upstreams change in documentation. While the `[DHCP]`
section might still work it is undocumented and we should probably not
be using it anymore. Users can just upgrade to the new option without
much hassle.
I had to create a bit of custom module deprecation code since the usual
approach doesn't support wildcards in the path.
What's happening now is that both cri-o and podman are creating
/etc/containers/policy.json.
By splitting out the creation of configuration files we can make the
podman module leaner & compose better with other container software.
Many options define their example to be a Nix value without using
literalExample. This sometimes gets rendered incorrectly in the manual,
causing confusion like in https://github.com/NixOS/nixpkgs/issues/25516
This fixes it by using literalExample for such options. The list of
option to fix was determined with this expression:
let
nixos = import ./nixos { configuration = {}; };
lib = import ./lib;
valid = d: {
# escapeNixIdentifier from https://github.com/NixOS/nixpkgs/pull/82461
set = lib.all (n: lib.strings.escapeNixIdentifier n == n) (lib.attrNames d) && lib.all (v: valid v) (lib.attrValues d);
list = lib.all (v: valid v) d;
}.${builtins.typeOf d} or true;
optionList = lib.optionAttrSetToDocList nixos.options;
in map (opt: {
file = lib.elemAt opt.declarations 0;
loc = lib.options.showOption opt.loc;
}) (lib.filter (opt: if opt ? example then ! valid opt.example else false) optionList)
which when evaluated will output all options that use a Nix identifier
that would need escaping as an attribute name.
extraModprobeConfig could be applied too late i.e. if the driver has been
loaded in initrd, while the harddrive is still encrypted.
Using a kernelParams works in all cases however.
This commit fixes #76620. It moves ExecStartPre and ExecStopPost to
preStart and postStop, as these options are composable. It thus allows
adding additional initialisation scripts or cleanup scripts to the systemd
unit of the docker container.
This option allows the user to control whether or not the docker container is
automatically started on boot. The previous default behavior (true) is preserved
NixOS has `virtualisation.docker.autoPrune.enable` for this
functionality; we should not do it every time a container starts up.
(also, some trivial documentation fixes)
- the `imageFile` option allows to load an image from a derivation
- the `dependsOn` option can be used to specify dependencies between container systemd units.

Previously, we were storing the leader pid in a runtime file and
signalled SIGRTMIN+4 manually.
In systemd 219, the `machinectl poweroff` command was introduced, which
does that for us.
The missing `\n` in the printf format string prevented multiple channels from
being logged.
The missing `nixpkgs=` in the `NIX_PATH` prevented `nixos-rebuild` from working
if the system configuration has any reference to `nixpkgs`.
Additionally:
* Use process substitution instead of piping printf to avoid creating a subshell.
* Set an empty `IFS` to avoid word splitting.
* Add the `-r` flag to `read` to avoid mangling backslashes.
Currently, LXD always use pkgs.zfs, even if boot.zfs.enableUnstable is set. This
change provides the option to change the LXC, LXD and ZFS packages, and
determines the default ZFS package based on zfs.enableUnstable.
Systemd dependencies for scripted mode
were refactored according to analysis in #34586.
networking.vswitches can now be used with systemd-networkd,
although they are not supported by the daemon, a nixos receipe
creates the switch and attached required interfaces (just like
the scripted version).
Vlans and internal interfaces are implemented following the
template format i.e. each interface is
described using an attributeSet (vlan and type at the moment).
If vlan is present, then interface is added to the vswitch with
given tag (access mode). Type internal enabled vswitch to create
interfaces (see openvswitch docs).
Added configuration for configuring supported openFlow version on
the vswitch
This commit is a split from the original PR #35127.
This makes ~2.5x speed up of an empty container instantiate, hence reduces
rebuild time of system with many declarative containers.
Note that this doesn't affect production systems much, becaseu those most
likely already include `minimal.nix` profile.
A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file
As part of the networking.* name space cleanup, connman should be moved
to services.connman. The same will happen for example with
networkmanager in a separate PR.
While switching NixOS configurations with both
networking.useNetworkd = true;
virtualisation.virtualbox.host.enable;
You often end up waiting for systemd-networkd-wait-online.service.
This happens because the vboxnet0 device doesn't have a carrier until
virtualbox machines are started, so networkd gets stuck in
"Configuring":
⇒ networkctl list
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier unmanaged
2 wlp2s0 wlan routable unmanaged
3 vboxnet0 ether no-carrier configuring
This updates the NixOS virtualbox host module to include a
RequiredForOnline=no statement in the generated 40-vboxnet0.network
file, so networkd doesn't consider it necessary for
systemd-networkd-wait-online.service to finish.
List all modules that *may* be required depending on individual container
configurations; don't expect that further modules can be loaded after boot.
