-# Debian Sid Base
-#
-# Currently we can build all our guests with cross-compilers in the
-# latest Debian release (Buster). However new compilers will first
-# arrive in Sid. However Sid is a rolling distro which may be broken
-# at any particular time. To try and mitigate this we use Debian's
-# snapshot archive which provides a "stable" view of what state Sid
-# was in.
-#
-
-# This must be earlier than the snapshot date we are aiming for
-FROM debian:sid-20190812-slim
