Keyboard not working after install

I installed latest CachyOS with KDE Plasma + LUKS enabled - after successful installation and reboot, the keyboard was not working in the LUKS text prompt.

I was able to resolve the issue by:
- Booting into the live environment
- Chrooting into the installed system
- Adjusting the keyboard order (move to front) in mkinit / initramfs configuration
- Regenerating the initramfs

After this, the keyboard worked correctly at the LUKS prompt.

I used a USB mac keyboard if that is relevant.
