Fixes#228141, which describes an issue where detaching Yubikey during the boot process
causes cryptsetup to write empty passphrase instead of the challenge-response salt stored
on the boot drive.
This fixes notably the fact that /dev/zfs was not usable anymore as a user,
and potentially other things.
Tracked in systemd upstream under issue number 28653, 28765.
This is an early preparation for systemd v254 which causes some patch reflows
and EFI-related cleanups to their new build system with elf2efi, requiring pyelftools
as a Python packge.
Historically, we allowed downgrade of DNSSEC, but some folks argue
this may decrease actually the security posture to do opportunistic DNSSEC.
In addition, the current implementation of (opportunistic) DNSSEC validation
is broken against "in the wild" servers which are usually slightly non-compliant.
systemd upstream recommended to me (in personal communication surrounding
the All Systems Go 2023 conference) to disable DNSSEC validation until
they work on it in a significant capacity, ideally, by next year.
it should be checking that it is not a broken symlink but bash

RequiredForOnline takes a boolean or a minimum operational state and an
optional maximum operational state. In the latter case, range values are
separated with colon.
Underneath, systemd-networkd’s reload is just `networkctl reload`. Per
`man networkctl`, calling `reload` is expected to fully handle new,
modified, and removed .network files, but it only handles *new* .netdev
files. For simplicity, assume .network -> reload and .netdev -> restart.
It’s desirable to perform reload instead of restart, as restart has the
potential to bring down interfaces, resulting in a loss of network
connectivity.
Just like with system-wide tmpfiles, call `systemd-tmpfiles --create
--remove` for users during activation. This fixes an issue where new
entries in a user's tmpfiles are not reflected after activation, only at
boot when the user service systemd-tmpfiles-setup.service runs or only
after running systemd-tmpfiles manually.
Before this commit there was no way to access (boot into) specialisation of previous generations from grub,even tho they are there.
This commit will add grub submenu for each generation if the generation has any specialisation.
Which will allow you to boot into them.

We should sometimes restart the units rather than reloading them so the
changes are actually applied. / and /nix are explicitly excluded because
there was some very old issue where these were unmounted. I don't think
this will affect many people since most people use fstab mounts instead
but I plan to adapt this behavior for fstab mounts as well in the future
(once I wrote a test for the fstab thingies).
When I boot there's a warning `stage-2-init: install: cannot change permissions of '/etc/nixos': No such file or directory`
because my /etc/nixos is a symlink to $HOME/dotfiles.
```
/etc/nixos -> /home/artturin/dotfiles
```

This avoids creating a build-time reference on `boot.kernelParams` if
the configuration does not use a kernel, i.e., `boot.kernel.enable` is
set to `false`.
There is only other `with` with a somewhat broad scope, `with pkgs`, but
it's used in a place where it would become awkward to change out. And
anyway its scope is rather limited still.
With a limited testing of all packaged GRUB 2 themes (pkgs.nixos-grub2-theme)
this is tested to work.
Without this change, the theme loading will error out (waiting for a key press).
With this change, the theme loads and works as expected.
The intent was to not pass the flag when installing as removable. In
reality there is a third case, where you may not want to touch EFI
variables, and not want to install as removable.
In that case, it would install to the generic \EFI\grub\grubx64.efi,
which is not a good choice in any cases. The operating system should
"own" their path under \EFI\ to be a good citizen [citation needed].
With this change, there can be only two paths GRUB can be installed to:
- \EFI\NixOS-boot\grubx64.efi
- \EFI\BOOT\bootx64.efi
This removes the surprising behaviour where GRUB may be installed to a
different location only because we configured NixOS not to touch EFI
variables.
It may be necessary under some configurations to install GRUB without
touching EFI variables, but to the NixOS-owned location.
This commit updates the binfmt magic-patterns using
f5e6786de4/scripts/qemu-binfmt-conf.sh
The patterns prior to this commit did not understand the difference
between mips32-*-* (32-bit void*,int) and mips64-*-*abin32 (32-bit
void*, 64-bit int). This commit corrects that.
In some setups, and especially with sytemd-networkd becoming more widely
used, networking.useDHCP is set to false. Despite this, it may be useful
to have dhcp in the initramfs.
Build logs show:

> configure: WARNING: non-linux system; not building swapon
So skip these on non-Linux

Example 10. of man page of systemd.network(5) shows:
```
Example 10. MacVTap
This brings up a network interface "macvtap-test" and attaches it to "enp0s25".
# /usr/lib/systemd/network/25-macvtap.network
[Match]
Name=enp0s25
[Network]
MACVTAP=macvtap-test
```
Which is a MACVTAP example and is currently unsupported in NixOS.
This is useful for people using "modern" technologies with virtual machines.
The whole option set was recommended against since mid-2019, and never
worked with the Raspberry Pi 4 family of devices.
We should have deprecated it in early 2020 for removal by 2021. At the
time I did not feel confident in making such a decision, and never
ended-up getting around to it.
The ***only*** supported-by-NixOS boot methods for AArch64 are
standards-based boot methods, namely UEFI or the pragmatically
almost-standard extlinux-compatible for U-Boot.
You can quote me on that.
According to networkd netdev's manpage:
```
Independent=
Takes a boolean. When true, the vxlan interface is created without any underlying network interface. Defaults to false, which means that a .network
file that requests this VXLAN interface using VXLAN= is required for the VXLAN to be created.
```
is a valid option for [VXLAN] section.
According to systemd.netdev manpage:
```
MACAddress=
Specifies the MAC address to use for the device, or takes the special value "none". When "none", systemd-networkd does not request the MAC address for
the device, and the kernel will assign a random MAC address. For "tun", "tap", or "l2tp" devices, the MACAddress= setting in the [NetDev] section is
not supported and will be ignored. Please specify it in the [Link] section of the corresponding systemd.network(5) file. If this option is not set,
"vlan" device inherits the MAC address of the master interface. For other kind of netdevs, if this option is not set, then the MAC address is
generated based on the interface name and the machine-id(5).
Note, even if "none" is specified, systemd-udevd will assign the persistent MAC address for the device, as 99-default.link has
MACAddressPolicy=persistent. So, it is also necessary to create a custom .link file for the device, if the MAC address assignment is not desired.
```
Therefore, `none` is an acceptable value.
These variables were previously used by the activation script
build commands, but are now embedded into those commands for
to improve reusability for an upcoming addition.
Without this change, GRUB installation on non-PC systems (such as
aarch64-linux) only works if boot.loader.grub.devices is set to exactly
`["nodev"]`. If boot.loader.grub.devices was any other value (including
the default `[]`), users got the error:
Died at /nix/store/an9ngv2vg95bdcy0ifsxlbkasprm4dcw-install-grub.pl line 586.
install-grub.pl verifies that if both $grub and $grubEfi are set, then
$grubTarget (e.g. i386-pc) and $grubTargetEfi (e.g. x86_64-efi) must
both be set, or the script will `die`. On non-PC systems, $grubTarget
is "".
When boot.loader.grub.devices is ["nodev"], $grub is set to null,
disabling non-EFI installation. But if a user has devices set for an
x86_64 config, or is using only mirroredBoots without setting devices,
they will hit this `die`.
This change sets $grub to "" if $grubTarget is "".
This helps with understanding the code.
We might make this not depend on environment variables later.
systemBuilderArgs is a form of global state, which isn't helpful.
This essentially backports
https://github.com/systemd/systemd/pull/27791. `systemd-networkd.service`
is sent the `SIGTERM` signal, but it is not required to be stopped
before `initrd-switch-root.target` is reached, despite the use of
`systemctl isolate initrd-switch-root.target`. This is because when
there is no ordering at all between two units, and a transaction stops
one and starts the other, the two operations can happen
simultaneously. This means the service could still be running when
`switch-root` actually occurs. Then, stage 2 systemd will see the
service still running and decide it doesn't need to add a start
operation for it to its initial transaction. Finally, the service
exits, but only after it's already too late. If, however, there is any
ordering at all between a stopping unit and a starting unit, then the
stop operation will be done first. This way, we ensure that the
service is properly exited before doing `switch-root`.
This is something to keep in mind going forward. There may be other
services that need this treatment. These `before` and `conflicts`
definitions are the correct way to ensure a unit is actually stopped
before you reach initrd-switch-root
This patch fixes "Argument list too long" build failure when passing a
list of store paths to system.extraDependencies that exceeds Linux'
MAX_ARG_STRLEN limit of 128 KiB. With the shortest possible derivation
names (one byte), the 128 KiB limit is equivalent to about 2850
derivations. With longer derivations names, the limit is hit earlier.
Fix this restriction.
it is now possible to supply a stratis pool uuid
for every filesystem, and if that filesystem
is required for boot, the relevant pool will be
started in the initramfs.
Enable using an erofs filesystem as one of the filesystems needed to
boot the system. This is useful for example in image based deployments
where the Nix store is mounted read only.
[erofs](https://docs.kernel.org/filesystems/erofs.html) offers multiple
benefits over older filesystems like squashfs. Skip fsck.erofs because
it is still experimental.
Note that this does not add to the `forbiddenDependenciesRegex`
code because that code check should be unaffected as it only checks
output dependencies, not build dependencies.
Build deps are added after that check, if those are enabled in the
first place.
Store the definition files in the initrd instead of reading them from
the Nix store in /sysroot.
This way, the initrd has to be re-generated every time the definition
files change. When the path to the defintion files instead of the
definition files themselves are embedded in the initrd, however, the
initrd also has to be re-generated every time. In this regard, this
change does not improve the status quo.
However, now systemd-repart also works reliable when the Nix store is
mounted separately from the root partition.
This change also enables new use-cases like creating partitions
necessary to boot the system. However, by default, the root partition
cannot be created on first boot because the systemd-repart service
requires a /sysroot to be mounted. Otherwise, systemd-repart cannot
determine the device to operate on.
Since v253, systemd-repart tries to create temporary directories in
/var/tmp. However, this directory doesn't exist in the initrd. This
commit adds an enviroment variable to re-use the existing /tmp directory
instead of /var/tmp.
When `nixpkgs.hostPlatform` != `nixpkgs.buildPlatform`, building the
top-level attribute fails since the bootspec portion of the system
builder tries to reference the host platform's `jq`. Change this to
reference the build platform's `jq`.
The `B` in bridge should be capitalized.
It currently leads to an evuluation error:
```
error: attribute 'sectionbridgeVLAN' missing

```
This removes the feature preview warning, enable by default bootspec,
adds a validation flag to prevent Go to go into build-time closure.
This will break all downstream users of bootspec as those changes are
not backward-compatible.
