When I wrote ts-debian-hvm-install, one of the problems (if I remember
correctly) was that our network infrastructure didn't support booting
EFI from PXE boot. I ended up making that disk image to sort of work
around this.

Per  https://www.debian.org/releases/stable/example-preseed.txt,
these runes look interesting.

# Additional repositories, local[0-9] available
#d-i apt-setup/local0/repository string \
#       http://local.server/debian stable main
#d-i apt-setup/local0/comment string local server
# Enable deb-src lines
#d-i apt-setup/local0/source boolean true
# URL to the public key of the local repository; you must provide a key
# or
# apt will complain about the unauthenticated repository and so the
# sources.list line will be left commented out
#d-i apt-setup/local0/key string http://local.server/key

Not sure if they will really end up in source.list though.
