# If we deploy in IPv6-only environments, and the students don't have IPv6
# connectivity, we want to offer a way to connect anyway. Our solution is
# to generate an HAProxy configuration snippet, that can be copied to a
# DualStack machine which will act as a proxy to our IPv6 machines.
# Note that the snippet still has to be copied, so this is not a 100%
# streamlined solution!
