This option allows adding the build closure of the system to its
runtime closure, enabling fully-offline rebuilds (as long as no new
packages are added).
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).
Previously, secrets were named according to the initrd they were
associated with. This created a problem: If secrets were changed whilst
the initrd remained the same, there were two versions of the secrets
with one initrd. The result was that only one version of the secrets would
by recorded into the /boot partition and get used. AFAICT this would
only be the oldest version of the secrets for the given initrd version.
This manifests as #114594, which I found frustrating while trying to use
initrd secrets for the first time. While developing the secrets I found
I could not get new versions of the secrets to take effect.
Additionally, it's a nasty issue to run into if you had cause to change
the initrd secrets for credential rotation, etc, if you change them and
discover you cannot, or alternatively that you can't roll back as you
would expect.
Additional changes in this patch.
* Add a regression test that switching to another grub configuration
with the alternate secrets works. This test relies on the fact that it
is not changing the initrd. I have checked that the test fails if I
undo my change.
* Persist the useBootLoader disk state, similarly to other boot state.
* I had to do this, otherwise I could not find a route to testing the
alternate boot configuration. I did attempt a few different ways of
testing this, including directly running install-grub.pl, but what
I've settled on is most like what a user would do and avoids
depending on lots of internal details.
* Making tests that test the boot are a bit tricky (see hibernate.nix
and installer.nix for inspiration), I found that in addition to
having to copy quite a bit of code I still couldn't get things to
work as desired since the bootloader state was being clobbered.
My change to persist the useBootLoader state could break things,
conceptually. I need some help here discovering if that is the case,
possibly by letting this run through a staging CI if there is one.
Fix#114594.

On some systems, EFI variables are not supported or otherwise wonky.
bootctl attempting to access them causes failures during bootloader
installations and updates. For such systems, NixOS provides the options
`boot.loader.efi.canTouchEfiVariables` and
`boot.loader.systemd-boot.graceful` which pass flags to bootctl that
change whether and how EFI variables are accessed.
Previously, these flags were only passed to bootctl during an install
operation. However, they also apply during an update operation, which
can cause the same sorts of errors. This change passes the flags during
update operations as well to prevent those errors.
Fixes https://github.com/NixOS/nixpkgs/issues/151336
The build of initrd-secrets can routinely fail for old boot entries
if the secrets have been removed or renamed in a later generation.
This always happens for generation 1, because it's built from the
NixOS installer and the paths differs by the mount point (i.e. /mnt).
The error is very confusing because it fails to mention it's about
an older generation and that it's somewhat harmless.
This commit turns the error into a warning for all generations but the
current, adds the name of the failed entry to the message and a note
explaining why it can happen.
apparently pandoc has changed behavior over the past releases, so the
files are no longer in sync. occasionally this requires edits
to the markdown source to not remove an anchor that was there
before (albeit wth a very questionable id), or where things were simply
being misrendered due to syntax errors.
