UEFI firmware does not have to be able to read ISO9660 filesystems, so
the El Torito mechanism provides a way to specify an embedded FAT32
image which contains files the UEFI firmware itself must be able to
read, such as UEFI executables. Once GRUB starts and reads its
configuration, it can access the ISO9660 filesystem to load other files.
This change removes the unused kernel, initrd, and GRUB font files from
the El Torito image, but keeps the GRUB configuration and UEFI
executables. These files have been present since EFI support was
originally introduced in commit 097c656. Other distribution ISOs, such
as Ubuntu 20.04, Fedora 35, and Windows 10 work this way too. This saves
24MiB on x86_64 and 61MiB on aarch64 ISOs.
GNOME 42 needs two wallpaper pictures – for the default (light)
colour scheme and for the dark one. Because we are clearing out
the paths in `gsettings-desktop-schemas` to prevent closure
from bloating, we need to set them in the NixOS module.
Since the wallpaper for the default colour scheme is dark,
will relegate it to the dark colour scheme and switch
to a light blue variant for the default colour scheme.
That one has inverted roundel for the NixOS logo but
it is the only light-ish background that has the logo
of the same size and placing as the dark wallpaper.
This module exposes a config.system.build.kexecBoot attribute,
which returns a directory with kernel, initrd and a shell script
running the necessary kexec commands.
It's meant to be scp'ed to a machine with working ssh and kexec binary
installed.
This is useful for (cloud) providers where you can't boot a custom image, but
get some Debian or Ubuntu installation.
With version 17 of Keycloak, the Wildfly based distribution was
deprecated in favor of the one based on Quarkus. The difference in
configuration is massive and to accommodate it, both the package and
module had to be rewritten.
This describes how to build your own installer medium with some custom
firmware/drivers, using an Intel MacBook as an example - on which WiFi
doesn't work out of the box, due to it being nonfree.
Fixes#15162.

This allows django-q to set the number of workers according to the CPU
core count and to show memory stats via `manage.py qmonitor`.
This also fixes a non-critical psutil error in paperless-ng-server.
Service:
- Fix misleading comment:
We could in fact implement password copying as a preStart script by
amending BindReadOnlyPaths, but adding an extra service is simpler.
Test:
- Add more detailed subtest names
- Simplify date check
It's already defined in `systemd/user.nix`.
This is a leftover from commit b6d50528dd
where all `systemd.user` settings were moved to `systemd/user.nix`.
