This would require support for bluez to run in the initrd. This is not
an easy ask though, since at that point there is no D-Bus, and there
is no persistency. BT pairing generally requires some kind of storage
though.
Bluez would have to learn special support for this, i.e. store such
pairings in an EFI variable or so.
Might as well just import /var/lib/bluetooth/*/linkkeys into the
initramfs then.
I think many BT controllers support storing link keys on the
controller itself though? Specifically for early boot (I kind of
recall that being mentioned in BitLocker context).
Dear Lennart, dear Mantas, dear Ulrich, thank you for taking the time to
reply.
FYI, as suggested, I opened a feature request on the Bluez GitHub
repository:
Support Bluetooth keyboards in initrd for entering LUKS passphrase
