# signals and orphaned processes are are handled correctly. The ca-certificate
# package is installed because the base Ubuntu image does not come with any
# certificate authorities.

# Note that /var/lib/apt/lists/* is cleaned up in the same RUN command as
# "apt-get update" to reduce the size of the image.
