This should barely increase the size of the initrd, because these are all symlinks.
With this, systems with dm-cache/lvmcache can also be booted, although the kernel modules for the relevant dm targets still need to be added to the initrd with boot.initrd.kernelModules.
If the pstore module is builtin, it nonetheless can take considerable
time to register a backend despite /sys/fs/pstore already appearing
mounted, so the condition is moved into the main script to extend
waiting for the backend to this case.
systemd's modprobe@.service does not require success so mount-pstore
executed despite a non-present pstore module, leading to an error about
the /sys/fs/pstore mountpoint not existing on CONFIG_PSTORE=n systems.
According to fstab(5), unlike last two fields `fs_freq` and `fs_passno`,
the 4-th field `fs_mntops` is NOT optional, though it works when omitted.
For best-practice and easier to be parsed by other programs, we should always
write `defaults` as default mount options for swap devices.
The `networking.hostname` option was changed to not permit periods
in names, due to a strict reading of RFC 1123. For users who need
the hostname to be fully qualified, the networking.hostName option
suggests using boot.kernel.sysctl."kernel.hostname" as a workaround.
This option works correctly at boot time, but every "nixos-rebuild
switch" will change the hostname back to the unqualified version.
This commit brings the activation script in line with the
documentation's recommendation.
This reverts commit d349582c07.
The workaround initially applied isn't necessary anymore, as 247.3
contains the following commit:
> 242fc1d261 network: fix IPv6PrivacyExtensions=kernel handling
… which fixes https://github.com/systemd/systemd/issues/18003.
If the machine is powered off when the zpool-trim timer is supposed to
trigger (usually around midnight) then the timer will be skipped
outright in favor of the next instance.
For desktop systems which are usually powered off at this time, zpool
trimming will never be run which can degrade SSD performance.
By marking the timer as `Persistent = yes` we ensure that it will run at
the first possible opportunity after the trigger date is reached.
We currently build CONFIG_IPV6=m.
This seems to be not really well-supported in mainline kernels - see
https://lore.kernel.org/netdev/20201115224509.2020651-1-flokli@flokli.de/T/#u
Compiling it as a module doesn't give too much benefit - even for people
who did explicitly set `enableIPv6` to false, the `ipv6` module was
still loaded, as soon as another module was loaded that requires it
(bridge,br_netfilter,wireguard,ip6table_mangle,sctp,…).
By compiling it in, we only loose the possibility to not add it to
`boot.kernelModules` anymore (as it's part of the kernel directly). The
space savings are negligible.
People wanting to disable IPv6 still get the appropriate sysctls and
options set (while having the kernel code loaded), nothing is really
changing here.
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

I really hope this finally fixes#99236: evaluation on Hydra.
This time I really did check basically the same commit on Hydra:
https://hydra.nixos.org/eval/1618011
Right now I don't have energy to find what exactly is wrong in the
commit, and it doesn't seem important in comparison to nixos-unstable
channel being stuck on a commit over one week old.
Conform to RFC 1123 [0], specifically to "2.1 Host Names and Numbers",
which allow starting host name with alphanumerical instead of alphabetical characters.
RFC 1123 updates RFC 952 [1], which is referenced in "man 5 hosts".

rfkill was subsumed by util-linux in 2017 [1], and the upstream has not
been updated in over 5 years [2]. This package shadows the rfkill from
util-linux, so it can be completely removed with no breaking changes,
because util-linux is in the base package set in nixos/system-path.

This change introduces more fine-grained requestEncryptionCredentials.
While previously when requestEncryptionCredentials = true, the
credentials for all imported pools and all datasets in these imported
pools were requested, it is now possible to select exactly the pools and
datasets for which credentials should be requested.
It is still possible to set requestEncryptionCredentials = true, which
continues to act as a wildcard for all pools and datasets, so the change
is backwards compatible.
This fixes a regression from 993baa587c which requires
networking.hostName to be a valid DNS label [0].
Unfortunately we missed the fact that the hostnames may also be empty,
if the user wants to obtain it from a DHCP server. This is even required
by a few modules/images (e.g. Amazon EC2, Azure, and Google Compute).

The `networking.interfaces.<name?>.proxyARP` option previously mentioned it would also enable IPv6 forwarding and `proxy_ndp`.
However, the `proxy_ndp` option was never actually set (the non-existing `net.ipv6.conf.proxy_arp` sysctl was set
instead). In addition `proxy_ndp` also needs individual entries for each ip to proxy for.
Proxy ARP and Proxy NDP are two different concepts, and enabling the latter
should be a conscious decision.
This commit removes the broken NDP support, and disables explicitly
enabling IPv6 forwarding (which is the default in most cases anyways)
Fixes#62339.
The `network-link-${i.name}` units raced with other things trying to
configure the interface, or ran before the interface was available.
Instead of running our own set of shell scripts on boot, and hoping
they're executed at the right time, we can make use of udev to configure
the interface *while they appear*, by providing `.link` files in
/etc/systemd/network/*.link to set MACAddress and MTUBytes.
This doesn't require networkd to be enabled, and is populated properly
on non-networkd systems since
https://github.com/NixOS/nixpkgs/pull/82941.
This continues clean-up work done in
https://github.com/NixOS/nixpkgs/pull/85170 for the scripted networking
stack.
The only leftover part of the `network-link-${i.name}` unit (bringing
the interface up) is moved to the beginning of the
`network-addresses-${i.name}` unit.

3c74e48d9c was a bit too much, it updated
permissions of all files recursively, causing files to be readable by
the group.
This isn't a problem immediately after bootup, but on a new activation,
as tmpfiles.d get restarted then, updating the permission bits of
now-existing files.
This updates the `Z` to be a `z` (the non-recursive variant), and adds a
`d` to ensure a directory is created (which should be covered by the
initrd shell script anyway)
boot.specialFileSystems is used to describe mount points to be set up in
stage 1 and 2.
We use it to create /run/keys already there, so sshd-in-initrd scenarios
can consume keys sent over through nixops send-keys.
However, it seems the kernel only supports the gid=… option for tmpfs,
not ramfs, causing /run/keys to be owned by the root group, not keys
group.
This was/is worked around in nixops by running a chown root:keys
/run/keys whenever pushing keys [1], and as machines had to have pushed keys
to be usable, this was pretty much always the case.
This is causing regressions in setups not provisioned via nixops, that
still use /run/keys for secrets (through cloud provider startup scripts
for example), as suddenly being an owner of the "keys" group isn't
enough to access the folder.
This PR removes the defunct gid=… option in the mount script called in
stage 1 and 2, and introduces a tmpfiles rule which takes care of fixing
up permissions as part of sysinit.target (very early in systemd bootup,
so before regular services are started).
In case of nixops deployments, this doesn't change anything.
nixops-based deployments receiving secrets from nixops send-keys in
initrd will simply have the permissions already set once tmpfiles is
started.

We should wait until after `multi-user.target` is triggered to allow
hardware to finish initializing, such as network devices and USB drives.
This ensures `powertop --auto-tune` sets more tunables to "Good".
Fixes#66820
This commit moves all the virtual console related options
to a dedicated config/console.nix NixOS module.
Currently most of these are defined in config/i18n.nix
with a "console" prefix like `i18n.consoleFont`,
`i18n.consoleColors` or under `boot` and are implemented
in tasks/kbd.nix.
Since they have little to do with actual internationalisation
and are (informally) in an attrset already, it makes sense to
move them to a specific module.

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
Just maching all network interfaces caused many breakages, see #18962
and #71106.
We already don't support the global networking.useDHCP,
networking.defaultGateway(6) options if networking.useNetworkd is
enabled, but direct users to configure the per-device
networking.interfaces.<name?>.… options.
We don't want to ignore config that can mess up machines. In general
this should always fail evaluation, as you think you are changing
behaviour and don't, which can easily create run-time errors we can
catch early.
With systemd version 243 network units with empty match block will
generate warnigs. The reasoning seems to be that the intended behaviour
is hard to infere. Being explicit about really meaning any interface is
the reasonable thing here.
We want to get rid of this mechanism in the long run but as long as we
do not have a replacement we should stick with it and keep it in
reasonable good shape.
This fixes a serious bug on NixOS with swraid where mdadm arrays weren't
properly stopped on shutdown. Rather than fixing the unit by adding
`Before=final.target` we completely move to upstream units, which uses
systemd shutdown hooks instead. This also drives down maintenance costs
for us.
Introduces a trim timer similar to the fstrim service.
According to zpool(8) for consumer hardware periodic manual TRIM
is preferred over automatic TRIM that ZFS implements.
The period of one week is based on recommendations of fstrim.
This is a refactor of how resolvconf is managed on NixOS. We split it
into a separate service which is enabled internally depending on whether
we want /etc/resolv.conf to be managed by it. Various services now take
advantage of those configuration options.
We also now use systemd instead of activation scripts to update
resolv.conf.
NetworkManager now uses the right option for rc-manager DNS
automatically, so the configuration option shouldn't be exposed.
Same as zfsUnstable for the moment.
We still keep the zfsUnstable expression as we likely
need it in the near future again.
Also remove spl since it is no longer needed.
With systemd v242 using the `Gateway` attribute of the `[Network]`
section will lead to "onlink" routes on all the device that are matched
by the default configuration (typically all devices) causing multiple
default routes (even on localhost).
We can only avoid that - while keeping our default route option - when
we mark the route as explicitly not on link. Only gateways that are
within a subnet of one of the assigned interface addresses will be
installed into the routing table.
Assert that autoResize is only used when fsType is explicitly set to a
supported filesystem: if it's set to "auto", the default, the required
resizing tools won't be copied into the initrd even if the actual
filesystem is supported.
27982b408e introduced a bug when
refactoring the encrypted-devices module, causing some encrypted
filesystem options to not be recognized anymore.
See e.g. https://hydra.nixos.org/build/88145490
This adds a NixOS option for setting the CPU max and min frequencies
with `cpufreq`. The two options that have been added are:
- `powerManagement.cpufreq.max`
- `powerManagement.cpufreq.min`
It also adds an alias to the `powerManagement.cpuFreqGovernor` option as
`powerManagement.cpufreq.governor`. This updates the installer to use
the new option name. It also updates the manual with a note about
the new name.
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.
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.

With a config like
{
networking.interfaces."lo".ip4 = [
{ address = "10.8.8.8"; prefixLength = 32; }
];
}
a nixos-rebuild switch would take a long time, and you'd see:
$ systemctl list-jobs

734450 sys-subsystem-net-devices-lo.device start running

systemd[1]: Timed out waiting for device sys-subsystem-net-devices-lo.device.
This removes the device dependency for `lo` and fixes this bug.
