# Runtime container
# ==================================
# The semaphore project's official container is built on
# alpine linux which uses musl instead of glibc. What does
# that mean? I don't really know and I don't really care, but
# the effect is that we can't build spectre/mpw on alpine
# which makes them mutually exclusive. Since we need both,
# we need a container to run both. And it's easier to repackage
# semaphore under not-alpine than it is to get spectre to build
# under alpine. So here we are.
