Bug#920353: debian-installer configuration on alpha

Package: debian-installer
Version: 20190118
Severity: wishlist
Tags: patch

Dear Maintainer,

- The debian installer currently downloads udebs 
from the buster/testing suite - which doesn't exist
for alpha and other non released architectures 
(powerpc is similar, see [1])

I propose to set

DEBIAN_RELEASE = unstable

in the alpha configuration file.

- It is required to include debian-ports-archive-keyring-udeb 
in netboot images to check Release signatures (it shouldn't
hurt in cdrom images too - to build a business-card cdrom or to 
download additional udebs)

Including pata-modules-${kernel:Version} would ease testing with
qemu.

Thanks in advance for your comments and for all your work on
the debian-installer.

Regards,
JH Chatenet
