The `platform` field is pointless nesting: it's just stuff that happens
to be defined together, and that should be an implementation detail.
This instead makes `linux-kernel` and `gcc` top level fields in platform
configs. They join `rustc` there [all are optional], which was put there
and not in `platform` in anticipation of a change like this.
`linux-kernel.arch` in particular also becomes `linuxArch`, to match the
other `*Arch`es.
The next step after is this to combine the *specific* machines from
`lib.systems.platforms` with `lib.systems.examples`, keeping just the
"multiplatform" ones for defaulting.
This is a temporary fix for #97433. A more proper fix has been
implemented upstream in systemd/systemd#17001, however until it gets
backported, we are stuck with ignoring the error.
After the backport lands, this commit should be reverted.
For UEFI setups, "device" will generally be the special value "nodev"
which represents not running grub-install at all. Using "nodev" for
boot mirrors should therefore be allowed.
The commit enforces buildPackages in the builder but neglects
the fact that the builder is intended to run on the target system.
Because of that, the builder will fail when remotely building a
configuration eg. with nixops or nix-copy-closure.
This reverts commit a6ac6d00f9.
Fixes error
Can't use an undefined value as an ARRAY reference at /nix/store/...-install-grub.pl line 642, <FILE> line 5.
with `/boot/grub/state` being:
```
grub
2.04
no
/dev/sda
/boot
```
I am not sure where the trailing empty line can come from; the script does not
seem to write it. In any case, now we handle that situation as well.
Further, ensure that `extraGrubInstallArgs` defaults to the empty array
if its key is not present in the `jsonState`.
For example, turns the error
cannot copy /nix/store/g24xsmmsz46hzi6whv7qwwn17myn3jfq-grub-2.04/share/grub/unicode.pf2 to /boot
into the more useful
cannot copy /nix/store/g24xsmmsz46hzi6whv7qwwn17myn3jfq-grub-2.04/share/grub/unicode.pf2 to /boot: Read-only file system
Useful for when you need to build grub modules into your grub kernel
to get a working boot, as shown in the added example.
To store this new value, we switch to more structural JSON approach.
Using one line per value to store in `/boot/grub/state` gets really messy when
the values are arrays, or even worse, can contain newlines (escaping would be
needed). Further, removing a value from the file would get extra messy
(empty lines we'd have to keep for backwards compatibility).
Thus, from now on we use JSON to store all values we'll need in the future.
This can be used to explicitly specify a specific dtb file, relative to
the dtb base.
Update the generic-extlinux-compatible module to make use of this option.
Some bootloaders might not properly detect the model.
If the specific model is known by configuration, provide a way to
explicitly point to a specific dtb in the extlinux.conf.
This option exposes the builder command used to populate an image,
honoring all options except the -c <path-to-default-configuration>
argument.
Useful to have for sdImage.populateRootCommands.
Special care needs to be taken w.r.t cross - the populate command runs
on the host platform, the activation script on the build platform (so
the builders differ)
The way this ends up being called with the raspberry pi 4 image builder
ends up not using the `-e` from the shebang.
In turn, the builds fails during cross-compilation. The wrong coreutils
ends up being used, but this is not made apparent.
The issue I faced is already fixed on master, but this ensures no one
ends up with a failed build "succeeding".
Memtest86+ doesn't support EFI, so unfree Memtest86 is used when EFI
support is enabled (systemd-boot currently also uses Memtest86 when
memtest is enabled).
