/usr/lib/udev/hwdb.d/70-local-keyboard.hwdb:28: Property expected, ignoring record with no properties.
With kernel 6.0 the legacy efi vars interface at /sys/firmware/efi/vars was removed
(https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit?h=v6.0&id=0f5b2c69a4cbe4166ca24b76d5ada98ed2867741).
The efibootmgr tool requires now to mount the efivarfs pseudo-filesystem on
/sys/firmware/efi/efivars. Enabling upstream EFI support for systemd is the easiest way to
get it mounted on EFI systems but still having correct (non-)support for legacy boot.
No additional files are added to the image.
