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

This reverts commit fb6d63f3fd.
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.
