padded cell: n. Where you put lusers so they can't hurt
anything. A program that limits a luser to a carefully restricted
subset of the capabilities of the host system (for example, the
`rsh(1)' utility on USG Unix). Note that this is different from an
iron box because it is overt and not aimed at enforcing security
so much as protecting others (and the luser) from the consequences
of the luser's boundless naivete (see naive). Also `padded cell
environment'.
