In order to fix
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.
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.
That version has a regression that leaves some machines unbootable.
While we wait for the fix (252.2) to land in master, this is a workaround that
should save people some pain.
Before this patch, the entry match condition always fails, causing all
entries being removed. The error is not noticed because later they are
re-generated.
Before this patch, the gen_number found by regex contains
"-specialisation-foo" if specialisation is used. As a result, applying
int() to gen_number raises ValueError, causing entries containing
a specialisation part not being removed.
mostly no rendering changes. some lists (like simplelist) don't have an
exact translation to markdown, so we use a comma-separated list of
literals instead.
our xslt already replaces double line breaks with a paragraph close and
reopen. not using explicit para tags lets nix-doc-munge convert more
descriptions losslessly.
only whitespace changes to generated documents, except for two
strongswan options gaining paragraph two breaks they arguably should've
had anyway.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
Handling of the string length condition in should_update
was broken, as evident with the log message
> leaving systemd-boot 246 in place (250.4 is not newer)
Discussion with @mweinelt came to the conclusion
that Python's "<" operator already does what we need,
so the should_update function can be dropped.
Fixes a30de3b849
Since, 4ddc78818e systemd-boot-builder
is broken in two ways:
* if no systemd-boot is currently installed *and* the NIXOS_INSTALL_BOOTLOADER
env variable is not set, it will try to run "bootctl update", which will fail
* if the currently installed systemd-boot version is newer than the version
we're about to install, it will also try to run "bootctl update", which will fail
This patch changes the behaviour,
* for the first case to still fail, but not even bother to try running
"bootctl update" and instead erroring out with an exception
* for the second case to leave the newer version in place, restoring
the pre - 4ddc78818e behaviour
To do the proper version check a new "should_update" helper function was introduced,
mimicing the compare_product C function from bootctl. If the following systemd
issue gets resolved, we would have a nice way to get rid of this function:

This change allows to again switch to a different NixOS configuration which contains
an older systemd-boot.

People running nixos-install in non-NixOS environments
occasionally run into the mktemp builtin not being loaded
into bash (yes, even NixOS' bash). Rather than try and
figure out why exactly that is happening, just use a known
good mktemp from coreutils.
