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.

This reverts commit 80665d606a.
Parsing the package version broke our systemd-boot builder test.
i.e. it won't be able to parse systemd-boot efi binaries coming from
ubuntu
We no longer use the faulty systemd-boot version so this code should no
longer be needed.
Before this commit there was no way to access (boot into) specialisation of previous generations from grub,even tho they are there.
This commit will add grub submenu for each generation if the generation has any specialisation.
Which will allow you to boot into them.

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.
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.
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 "".
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).
