For Sugar on a Stick, the *device mapper* service dmsetup provides a
status report
which shows the consumption of space allocated for persistent storage, the
snapshot overlay file. *Sugar Cellar* is a small, utility script which uses
that service to allow for Learner testing and discovery. This will help
Learners manage their storage resources and learn ways to economize limited
resources. [http://wiki.sugarlabs.org/go/LiveOS_image]

Sugar Cellar is a component of Sugar on a Stick/Sugar
