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:

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.
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 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
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.
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.
The `B` in bridge should be capitalized.
It currently leads to an evuluation error:

https://github.com/NixOS/nixpkgs/issues/114552 (profile name with
special characters), all OSError have been ignored while only the OSError
with errno 22 (invalid argument) could has been ignored.
The drawback of ignoring all OSError is that the "No space left on
device" error is also ignored. When the /boot doesn't have enough
available disk space, the switch-to-configuration script succeeds
while the boot menu has not been updated: the user thinks it's system
has been updated, but on the next reboot it is actually rollbacked.
Extension based matching for Windows targets define it '.exe' but kernel
documentation explicitly states it should be passed "without the .".

`systemd-growfs@.service` and `systemd-growfs-root.service` became real units since:
50072ccf1b
we need to add them to the nixos module so growfs works again
systemd now requires the /tmp mount point in the initrd cpio archive
since https://github.com/systemd/systemd/pull/25723
setting `"/tmp/.keep".text` will create the directory.
this fixes a boot failure:
```
(sd-gens): Failed to overmount /tmp/: No such file or directory
```
This reverts commits f5483464d5 and
6b9583e5e1.
Ideally, we shouldn't cause friction for users that bump `stateVersion`,
and I'd consider having to switch and/or manually hardcode a UID/GID
to supress the warning friction. I think it'd be more beneficial to, in
this rare case of an ID being missed, just let it be until more
discussion happens surrounding this overall issue.
See https://github.com/NixOS/nixpkgs/pull/217785 for more context.
Being able to override `boot.initrd.systemd.initrdBin` with `boot.initrd.systemd.extraBin` is a desirable behavior, so this PR changes the `ln -s` command to `ln -sf` to force link even if the file already exists.
{manpage} already exapnds to a link but akkoma wants to link to
a specific setting. split the mention for clarity.
networkd just straight up duplicated what {manpage} generates anyway, so
that link can go away completely.
Since this feature's inception, we've compiled a binary that uses OpenSSL
to perform PBKDF-SHA512 during the extra-utils build. In addition to this
being inefficient, it broke as of 6ea1a2a1be,
which switched the extra-utils derivation to use stdenvNoCC.
For now, I think the path of least resistence is to move the pbkdf-sha512
build to its own derivation, to fix the breakage, as well as improving
the efficiency of the extra-utils build.
(I do believe that at some point, we should revisit this binary -- perhaps
rewriting it -- as Clang even just on its default settings emits more
warnings than you'd want to see in a security-related codebase when
compiling it.)
We shouldn't be creating a systemd.services.systemd-binfmt value when
the upstream unit isn't being pulled in, because it results in a
service unit file with no ExecStart line
this converts meta.doc into an md pointer, not an xml pointer. since we
no longer need xml for manual chapters we can also remove support for
manual chapters from md-to-db.sh
since pandoc converts smart quotes to docbook quote elements and our
nixos-render-docs does not we lose this distinction in the rendered
output. that's probably not that bad, our stylesheet didn't make use of
this anyway (and pre-23.05 versions of the chapters didn't use quote
elements either).
also updates the nixpkgs manual to clarify that option docs support all
extensions (although it doesn't support headings at all, so heading
anchors don't work by extension).
