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
