#
#  pigz, py-pip, py-twisted, py-yaml, python, tar: Used by Umpire
#  (buzybox tar doesn't support -I, which is used in file_utils.ExtractFile)
#  gnupg, python-gnupg: Used by umpire/service/dkps and archiver
#  rsync: Used by umpire/service/rsync
#  jq: Will be used by umpire in future.
#
#  py-protobuf: Dependencies that are used by some board's shop_floor
#
#  nginx, uwsgi-python: Used by Dome.
#
#  apache2-utils, openssl: Used by Overlord setup.sh
#
#  util-linux: For GNU mount since busybox mount doesn't support offset.
#  coreutils: For GNU mktemp since busybox mktemp doesn't support --tmpdir.
