# This is the script that our Jenkins/CI system runs. Yes, it is a bit messy.

#
# For running this on your own computer (jessie), see https://wiki.debian.org/mk-sbuild
# for information on setting up sbuild.
# Short version: 1) apt-get install ubuntu-dev-tools 2) mk-sbuild jessie
#
# To CHANGE the golden image: sudo schroot -c source:jessie-amd64 -u root
# To ENTER an image snapshot: schroot -c jessie-amd64
# To BUILD within a snapshot: sbuild -A -d jessie-amd64 PACKAGE*.dsc
