alpine-extended-3.16.0-x86_64.iso lacks linux-firmware-none

Installing alpine 3.16 with the extended iso fails without networking

# setup-disk -m sys /mnt
Installing system on /dev/xvda1:
extlinux: Not a directory: /mnt/boot
ERROR: unable to select packages:
  linux-firmware-none (no such package):
    required by: world[linux-firmware-none]

# find /media/cdrom -name linux-firmware-none\*
# 

There are other firmware apk's on the extended iso but linux-firmware-none is missing

Tested with: alpine-extended-3.16.0-x86_64.iso
