What the end user wants -- "shrink or expand a the partition" is also
"shrink or expand the fs". So the fs tools must support shrinking and

IME, any operator/hw/sw error in the multi-step process is fatal. More
to the point, any powerloss during the process is fatal, and the
process of FS shrinking takes ages.

The context of my comment is an OLPC dev list: we are trying to build
fail-safe tools here for deployment in the field.
