# Script to set up a base image with just monit, collectd, and pull.
#
# This script is used on a temporary GCE instance. Just run it on a fresh
# wheezybackports image and then capture a snapshot of the disk. Any image
# started with this snapshot as its image should be immediately setup to
# install applications via Skia Push.
#
# For more details see ../../push/DESIGN.md.
