#!/bin/sh
# Shell script used to test the Remote MIB (RMIB) functionality.
# We test a couple of things here, using the rmibtest service and test87:
# - some cases where remote MIB subtree registration should fail;
# - a new mount point (minix.rtest) with a small tree behind it, on which we
# test some basic reads and writes on an integer pointer and a function;
# - shadowing of an existing subtree (minix.test) with a similarly looking
# subtree, which we then subject to a subset of test87;
# - resource accounting, making sure everything is the same before and after.
