USING THE CHROOTS

To CHANGE the golden image: sudo schroot -c ${SCHROOT_NAME} -source -u
root

To ENTER an image snapshot: schroot -c $SCHROOT_NAME
To BUILD within a snapshot: sbuild -A -d $SCHROOT_NAME $PACKAGE *.dsc
for example, to update the packages in a sid-amd64 golden image:

schroot -c sid-amd64-source -u root -- sh -c "apt-get -qq update && apt-get -qy upgrade && apt-get clean" </dev/null
