InitramFS Generation with Paired Bluetooth Device Metadata #4214

For that, I think you'd be better served by rpm-ostree initramfs --enable. And you'll likely also want to add --arg=--add --arg=bluetooth.

Unfortunetely that only includes files inside /etc but not /var/lib/bluetooth so you miss the paired device metadata.

Gotcha. Thanks for bringing this up. We currently don't expose /var to dracut but it could make sense to do so for use cases like this. Can you file a separate issue for this?

As we discussed in above thread, currently it's possible for us to include bluetooth modules inside the generated initramfs image. Since it doesn't include files inside /var/lib/bluetooth, it's not possible to use bluetooth keyboards during LUKS decryption.

One complexity here is that inherently you end up with two copies of the data. And so anytime the bluetooth pairing is changed, the initramfs would need to be regenerated - even outside an OS update.
