Hi

Note that the patching to add hyperv_keyboard seems unnecessary,
since that module is in the drivers/input/serio
https://github.com/torvalds/linux/blob/d54f486035fd89f14845a7f34a97a3f5da4e70f2/drivers/input/serio/Makefile#L32
as far as I can see.

And dracut now includes all of those module
https://github.com/dracutdevs/dracut/blob/056/modules.d/90kernel-modules/module-setup.sh#L57
since version 45

That dracut change to include all HID Devices was one of the items I saw 
in the changelog that prompted me to suggest to update dracut in Ipfire



Regards Alf
