Running systemd-timesyncd with an empty list of timeservers to sync from
does not work.
In case an empty list is configured here, systemd will fall back to its
compiled-in defaults, which NixOS sets to `{0..4}.nixos.pool.ntp.org`,
as per https://github.com/systemd/systemd/blob/main/docs/DISTRO_PORTING.md#ntp-pool
This has caused some confusion. Explicitly document this, and describe
how to disable timesyncd.
We need to make sure systemd-tmpfiles-setup.service ran before we
start systemd-binft.service. Otherwise it might fail to start
due to non-existant files
Fixes#295365
This ensures a ".dtb" PE section makes it into the UKI so systemd-stub
can install the correct devicetree for use by the Linux kernel. This is
often needed on systems that boot with u-boot since the devicetree used
by u-boot is often a paired down version of what the Linux kernel needs.
On those kinds of boards, the lack of this PE section means that u-boot
will end up installing its internal devicetree into the UEFI
configuration table, which is what the Linux kernel ends up using.
Without sort-keys specified on entries, the entries are sorted only by
file name (in decreasing order, so starting at the end of the alphabet!),
without taking any other fields into account (see
[the boot loader specification reference][1]).
Moreover, entries without a sort-key are always ordered after all
entries with a sort-key, so by not adding a sort-key to the NixOS ones,
we cannot add a sort-key to any other entry while keeping it below the
NixOS entries.
So currently we have options to set the file names for additional entries like
memtest and netbootxyz.
However, as mentioned above, the sorting by file name is not very intuitive and
actually sorts in the opposite order of what is currently mentioned in the option
descriptions.
With this commit, we set a configurable sort-key on all NixOS entries,
and add options for setting the sort-keys for the memtest and netbootxyz
entries.
The sorting by sort-key is more intuitive (it starts at the start of the
alphabet) and also takes into account the machine-id and version for entries
with identical sort-keys.
We use a bootspec extension to store the sort keys, which allows us to
redefine the sort key for individual specialisations without needing any
special casing.

The maximum length for a GPT label supported by systemd is 36
characters. When a repart definition contains a label that is longer
than the supported maximum length, it is ignored by systemd-repart and
a log message is produced.
The new assertion makes this obvious to the user at evaluation time,
allowing them to either drop the property entirely or choose a supported
label within the length limit instead.
Since we are not in a `callPackage` context, dependencies in
`nativeBuildInputs` don't get spliced to the buildPlatform, causing a
cross-compiled nixos system to fail at this step when running mypy built
for the hostPlatform.
Before there was a kernel modules path named kernel-modules which then got turned
into linux-X.X.XX-modules-shrunk. Now the unshrunk package is called linux-X.X.XX-modules
and gets turned into X.X.XX-modules-shrunk.
this lets us *dis*able filesystem explicitly, as is required by e.g. the
zfs-less installer images. currently that specifically is only easily
possible by adding an overlay that stubs out `zfs`, with the obvious
side-effect of also removing tooling that could run without the kernel
module loaded.
These should be defaults as they're pretty reasonable to want to
override as a user. Unsure how to change the slice defaults to be
overridable, that should probably be a later conversation.
Lists are convenient to have in sysupdate configuration when using
multiple `MatchPattern` under `Target` when the target can have multiple
filenames. This use-case is helpful for BootLoaderSpec bootcounting where the target file on
disk can have multiple filenames, and in order for sysupdate to properly
ensure only N number of instances of this target exist at one time, we
need to have multiple match patterns.
Previously any user-provided config for boot.uki.settings would need to
either specify a full set of config for ukify or a combination of
mkOptionDefault to merge the "settings" attribute set with the module's
defaults and then mkOverride or mkForce to override a contained
attribute.
Now it is possible to trivially override parts of the module's default
config, such as the initrd or kernel command line, but overriding the
full set of settings now requires mkOverride / mkForce.
There were several modules, critically including NetworkManager, which
were not prepared for this change. Most of the change was good,
however. Let's bring back the dependency and change the assertion to a
warning for now.
Previously we required network-online.target for multi-user.target. This
has made a lot of people very angry and has been widely regarded as a
bad move (or at least, very nonstandard):
15d761a525 (commitcomment-128564097)
This was done because of fragile tests and services declaring
dependencies on multi-user.target when they meant network-online.target.
Let's rip off the bandaid and fix our tests.
This makes it easier to reason about what variables are inserted during packaging.
We also make sure that template file is also valid python syntax, which makes editor errors go away during development.
Removed patches:
- 0007-Fix-hwdb-paths.patch
The directory we want seems to already be included in the list. Is there
a reason why we want to restrict it further?
- 0010-build-don-t-create-statedir-and-don-t-touch-prefixdi.patch
This patch has little to do with how the meson.build file looks now. The
new patch 0017 is the successor to this one.
- 0015-pkg-config-derive-prefix-from-prefix.patch
This is fixed upstream. We don't need this anymore.
The example systemd-sysupdate transfer name has a ".conf" suffix,
although the files on the final system are already appended with this
suffix, so the file ends up being "transfer-name.conf.conf". Remove the
suffix in the example so that users will get a transfer filename they
expect.
Systemd-repart will use loopback devices for partition creation if it is
able to, and will fallback to doing "offline" partition creation writing
data directly to files. From what I see looking at the repart code,
there are specific features that cannot be taken advantage of when not
using loopback devices (e.g. no BTRFS subvolumes in systemd v255) and in
certain places they have to perform some manual re-sizing work that can
otherwise be avoided.
A bootspec could remove the `initrdSecrets` attribute and is a perfectly valid bootspec, as can be seen
in the bootspec.cue.
This makes the builder not fail upon missing `initrdSecrets`.
