This updates the ipu6 driver and firmware to a more recent version,
which seems to at least work in Chrom{e,ium}.
ipu6-drivers now relies on the in-kernel ipu6 kernel driver, so we
update our logic and metadata for it.
This allows settings multiple scripts in `.custom.start` and
`.custom.end`, as Gamemode reads them back out into a list.
This is slightly annoying, as *any* duplicate keys will appear multiple
times, while gamemode will only accept the last one for most keys
(clobbering previous ones). Ideally, it would be possible to only enable
`listsAsDuplicateKeys` for scripts, but this does not seem to be
possible in `pkgs.formats.ini`.
When installing NixOS on a machine with Windows, the "easiest" solution
to dual-boot is re-using the existing EFI System Partition (ESP), which
allows systemd-boot to detect Windows automatically.
However, if there are multiple ESPs, maybe even on multiple disks,
systemd-boot is unable to detect the other OSes, and you either have to
use Grub and os-prober, or do a tedious manual configuration as
described in the wiki:
https://wiki.nixos.org/w/index.php?title=Dual_Booting_NixOS_and_Windows&redirect=no#EFI_with_multiple_disks
This commit automates and documents this properly so only a single line
like
boot.loader.systemd-boot.windows."10".efiDeviceHandle = "HD0c2";
is required.
In the future, we might want to try automatically detecting this
during installation, but finding the correct device handle while the
kernel is running is tricky.
Currently if a timezone was selected explicitly, the service will
silently override the value, essentially ignoring what is meant to be a
a deliberate choice of option. This may cause confusion as to why the
option is not doing anything when this service is enabled, particularly
in more complex set-ups after some time.
This will simply make the choice deliberate from the user's part, either
by having to remove the option or lowering its priority as a recognition
that it may be ignored.
This change was inspired by the `services.tzupdate` module, which does
the same.
