But it lacks information:
% apt-cache policy
Package files:
100 /var/lib/dpkg/status
release a=now
500 http://storage sid/non-free Packages
release o=Debian,a=unstable,l=Debian,c=non-free
origin ftp.de.debian.org
500 http://storage sid/contrib Packages
release o=Debian,a=unstable,l=Debian,c=contrib
origin ftp.de.debian.org
500 http://storage sid/main Packages
release o=Debian,a=unstable,l=Debian,c=main
origin ftp.de.debian.org
Now is that
http://storage/debian/sid/main/binary-amd64/Packages
or
http://storage/mirror/debian/sid/main/binary-amd64/Packages
?
You just don't have all the info.

Ah, then I misunderstood what you add and when.

Nothing wrong with picking ftp.debian.org from the mirror list if one
is in us. D-I takes the full list, filters out mirrors that carry the
requested arch and then tries to pick one from the country the locales
are set to. Otherwise the user gets asked to pick one afaik.
So nothing says the mirror you end up with on i386 will have arm
packages.

Ucf is neccessary (not strictly speaking but it is a very good idea)
whenever you generate a conffile instead of shipping a premade file
in the package. If you have the option of having a primary mirror
or an empty file then you can't ship the file. So ucf becomes your
friend.
