<une works as well, but instead of adding an extra drive, I just add an extra
partition (on each raided drive) that is not raided and boot from that
(as described earlier)in this thread.)

For fixing PR 44982 I'd probably concemtrate on UEFI booting, and  enhance
that version of /boot to understand raid (properly, the way the kernel does)
and gpt inside that raid.   Even booting from raid5 should be possible.
