# This Docker image can change from one build to another, because the upstream
# Debian/Ubuntu package index is continuously updated and we have to run
# `apt-get update` in here.
#
# The only way to make this a part of our reproducible build system is to build
# it once, upload it to Docker Hub and make sure it's being pulled regularly so
# it's not deleted after 6 months of inactivity.

# We delete the static Qemu binary when we're done with it, because it might
# not run on other systems. Let the child image copy it again.
