d-i Alpha 3 seems unusable for qemu-system-aarch64

Hi Debian Arm users,

I tried Bullseye d-i Alpha3 released on December 6 for
building a qemu disk image usable by qemu-system-aarch64.
To me, Alpha 3 d-i seems almost unusable for that purpose.
I filed a report at
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=976808

If you have interest, please have a look.  Ryutaroh
